Introduction

In this article, we will explore the concept of finding the derivative of a function that involves the product of two exponential functions. The function in question is $f(x) = \left(-8x^2 - 4\right)^7 \left(-6x^2 + 8\right)^{13}$. We will use the product rule and chain rule of differentiation to find the derivative of this function.

The Product Rule

The product rule is a fundamental rule in calculus that states that if we have a function of the form $f(x) = u(x)v(x)$, then the derivative of $f(x)$ is given by $f'(x) = u'(x)v(x) + u(x)v'(x)$. This rule can be extended to the product of more than two functions.

The Chain Rule

The chain rule is another fundamental rule in calculus that states that if we have a function of the form $f(x) = g(h(x))$, then the derivative of $f(x)$ is given by $f'(x) = g'(h(x)) \cdot h'(x)$. This rule can be extended to the composition of more than two functions.

Finding the Derivative of $f(x)$

To find the derivative of $f(x)$, we will use the product rule and chain rule. We can rewrite $f(x)$ as $f(x) = u(x)v(x)$, where $u(x) = \left(-8x^2 - 4\right)^7$ and $v(x) = \left(-6x^2 + 8\right)^{13}$.

Finding the Derivative of $u(x)$

To find the derivative of $u(x)$, we will use the chain rule. We can rewrite $u(x)$ as $u(x) = g(h(x))$, where $g(x) = x^7$ and $h(x) = -8x^2 - 4$. Then, the derivative of $u(x)$ is given by $u'(x) = g'(h(x)) \cdot h'(x)$.

import sympy as sp
x = sp.symbols('x')

u = (-8*x**2 - 4)**7

u_prime = sp.diff(u, x)
print(u_prime)

Finding the Derivative of $v(x)$

To find the derivative of $v(x)$, we will use the chain rule. We can rewrite $v(x)$ as $v(x) = g(h(x))$, where $g(x) = x^{13}$ and $h(x) = -6x^2 + 8$. Then, the derivative of $v(x)$ is given by $v'(x) = g'(h(x)) \cdot h'(x)$.

import sympy as sp

x = sp.symbols('x')

v = (-6*x**2 + 8)**13

v_prime = sp.diff(v, x)
print(v_prime)

Finding the Derivative of $f(x)$

Now that we have found the derivatives of $u(x)$ and $v(x)$, we can use the product rule to find the derivative of $f(x)$. The derivative of $f(x)$ is given by $f'(x) = u'(x)v(x) + u(x)v'(x)$.

import sympy as sp

x = sp.symbols('x')

f = (-8x**2 - 4)**7 * (-6x**2 + 8)**13

f_prime = sp.diff(f, x)
print(f_prime)

Conclusion

In this article, we have found the derivative of the function $f(x) = \left(-8x^2 - 4\right)^7 \left(-6x^2 + 8\right)^{13}$ using the product rule and chain rule of differentiation. We have used the product rule to find the derivative of the product of two exponential functions, and the chain rule to find the derivative of each exponential function. The final derivative of $f(x)$ is given by $f'(x) = u'(x)v(x) + u(x)v'(x)$.

Future Work

In the future, we can use the derivative of $f(x)$ to find the critical points of the function, and to determine the maximum and minimum values of the function. We can also use the derivative of $f(x)$ to find the rate of change of the function with respect to the variable $x$.

Introduction

In our previous article, we found the derivative of the function $f(x) = \left(-8x^2 - 4\right)^7 \left(-6x^2 + 8\right)^{13}$ using the product rule and chain rule of differentiation. In this article, we will answer some common questions that readers may have about finding the derivative of this function.

Q: What is the product rule of differentiation?

A: The product rule of differentiation is a fundamental rule in calculus that states that if we have a function of the form $f(x) = u(x)v(x)$, then the derivative of $f(x)$ is given by $f'(x) = u'(x)v(x) + u(x)v'(x)$.

Q: What is the chain rule of differentiation?

A: The chain rule of differentiation is another fundamental rule in calculus that states that if we have a function of the form $f(x) = g(h(x))$, then the derivative of $f(x)$ is given by $f'(x) = g'(h(x)) \cdot h'(x)$.

Q: How do I find the derivative of an exponential function?

A: To find the derivative of an exponential function, you can use the chain rule. For example, if we have a function of the form $f(x) = e^{g(x)}$, then the derivative of $f(x)$ is given by $f'(x) = e^{g(x)} \cdot g'(x)$.

Q: How do I find the derivative of a product of two functions?

A: To find the derivative of a product of two functions, you can use the product rule. For example, if we have a function of the form $f(x) = u(x)v(x)$, then the derivative of $f(x)$ is given by $f'(x) = u'(x)v(x) + u(x)v'(x)$.

Q: What is the difference between the product rule and the chain rule?

A: The product rule is used to find the derivative of a product of two functions, while the chain rule is used to find the derivative of a composite function.

Q: Can I use the product rule and chain rule together?

A: Yes, you can use the product rule and chain rule together to find the derivative of a function that involves the product of two composite functions.

Q: How do I find the derivative of a function that involves the product of two exponential functions?

A: To find the derivative of a function that involves the product of two exponential functions, you can use the product rule and chain rule together. For example, if we have a function of the form $f(x) = e^{g(x)} \cdot e^{h(x)}$, then the derivative of $f(x)$ is given by $f'(x) = e^{g(x)} \cdot h'(x) + e^{h(x)} \cdot g'(x)$.

Q: Can I use a calculator to find the derivative of a function?

A: Yes, you can use a calculator to find the derivative of a function. However, it's always a good idea to check your work by hand to make sure that the calculator is giving you the correct answer.

Q: How do I check my work when finding the derivative of a function?

A: To check your work when finding the derivative of a function, you can use the following steps:

1. Plug in a value for $x$ into the function and the derivative.
2. Simplify the expression and make sure that it is equal to the derivative.
3. Check your work by plugging in a different value for $x$ and making sure that the expression is still equal to the derivative.

Conclusion

In this article, we have answered some common questions that readers may have about finding the derivative of the function $f(x) = \left(-8x^2 - 4\right)^7 \left(-6x^2 + 8\right)^{13}$. We have also provided some tips and tricks for finding the derivative of this function, as well as other functions that involve the product of two exponential functions.
