Introduction

Inverse functions are a crucial concept in mathematics, and they play a vital role in various fields, including algebra, calculus, and engineering. In this article, we will focus on finding the inverse of a quadratic equation, specifically the equation $y = 5x^2 + 10$. To find the inverse, we need to simplify the given equation and express it in terms of $x$ as a function of $y$. In this discussion, we will explore the different options and determine which equation can be simplified to find the inverse of the given quadratic equation.

Understanding the Concept of Inverse Functions

Before we dive into the problem, let's briefly review the concept of inverse functions. An inverse function is a function that undoes the action of the original function. In other words, if we have a function $f(x)$, its inverse function $f^{-1}(x)$ will take the output of $f(x)$ and return the original input. In mathematical terms, if $f(x) = y$, then $f^{-1}(y) = x$.

Simplifying the Given Equation

To find the inverse of the given equation $y = 5x^2 + 10$, we need to simplify it and express it in terms of $x$ as a function of $y$. Let's start by isolating the term with $x$.

y = 5x^2 + 10

Option A: $x = 5y^2 + 10$

Let's analyze the first option, $x = 5y^2 + 10$. To determine if this is the correct equation, we need to substitute $y = 5x^2 + 10$ into the equation and see if we get the original equation.

x = 5y^2 + 10
x = 5(5x^2 + 10)^2 + 10

As we can see, the equation does not simplify to the original equation, so this is not the correct option.

Option B: $\frac{1}{y} = 5x^2 + 10$

Now, let's analyze the second option, $\frac{1}{y} = 5x^2 + 10$. To determine if this is the correct equation, we need to substitute $y = 5x^2 + 10$ into the equation and see if we get the original equation.

\frac{1}{y} = 5x^2 + 10
\frac{1}{5x^2 + 10} = 5x^2 + 10

As we can see, the equation does not simplify to the original equation, so this is not the correct option.

Option C: $-y = 5x^2 + 10$

Now, let's analyze the third option, $-y = 5x^2 + 10$. To determine if this is the correct equation, we need to substitute $y = 5x^2 + 10$ into the equation and see if we get the original equation.

-y = 5x^2 + 10
-(5x^2 + 10) = 5x^2 + 10
-5x^2 - 10 = 5x^2 + 10

As we can see, the equation does not simplify to the original equation, so this is not the correct option.

Option D: $y = \frac{1}{5}x^2 + \frac{1}{10}$

Now, let's analyze the fourth option, $y = \frac{1}{5}x^2 + \frac{1}{10}$. To determine if this is the correct equation, we need to substitute $y = 5x^2 + 10$ into the equation and see if we get the original equation.

y = \frac{1}{5}x^2 + \frac{1}{10}
5x^2 + 10 = \frac{1}{5}x^2 + \frac{1}{10}

As we can see, the equation does not simplify to the original equation, so this is not the correct option.

Conclusion

After analyzing all the options, we can conclude that none of the given equations can be simplified to find the inverse of the given quadratic equation $y = 5x^2 + 10$. However, we can try to find the inverse by using a different approach.

Finding the Inverse Using a Different Approach

To find the inverse of the given equation, we can start by isolating the term with $x$.

y = 5x^2 + 10
x^2 = \frac{y - 10}{5}
x = \pm \sqrt{\frac{y - 10}{5}}

As we can see, the inverse of the given equation is $x = \pm \sqrt{\frac{y - 10}{5}}$. This is the correct equation, and it can be verified by substituting $y = 5x^2 + 10$ into the equation.

Conclusion

In conclusion, we have found the inverse of the given quadratic equation $y = 5x^2 + 10$ using a different approach. The inverse is $x = \pm \sqrt{\frac{y - 10}{5}}$, and it can be verified by substituting $y = 5x^2 + 10$ into the equation. This demonstrates that the inverse of a quadratic equation can be found using various methods, and it is essential to understand the concept of inverse functions to solve problems in mathematics and other fields.

Final Answer

The final answer is: $\boxed{x = \pm \sqrt{\frac{y - 10}{5}}}$
