Introduction
In mathematics, functions are used to describe relationships between variables. Given a function, we can manipulate it to create new functions. In this article, we will explore how to find the value of g(x) given the function f(x) = 4^x.
Understanding the Function f(x)
The function f(x) = 4^x is an exponential function. This means that as x increases, the value of f(x) increases exponentially. For example, if x = 2, then f(x) = 4^2 = 16. If x = 3, then f(x) = 4^3 = 64.
Manipulating the Function f(x)
To find g(x), we need to manipulate the function f(x) = 4^x. We can do this by using algebraic operations such as addition, subtraction, multiplication, and division.
Option A:
Let's start by analyzing option A: . To determine if this is equal to g(x), we need to manipulate the function f(x) = 4^x to match this expression.
We can rewrite f(x) = 4^x as f(x) = 4^(x-2+2). Using the properties of exponents, we can simplify this expression to f(x) = 4^(x-2) * 4^2.
Since 4^2 = 16, we can rewrite f(x) = 4^(x-2) * 16. This is equivalent to f(x) = 16 * 4^(x-2).
Now, let's compare this expression to option A: . We can see that they are equivalent, but with a constant factor of 16.
Option B:
Let's analyze option B: . To determine if this is equal to g(x), we need to manipulate the function f(x) = 4^x to match this expression.
We can rewrite f(x) = 4^x as f(x) = 4^x + 0. However, this is not equivalent to option B, since the constant term is 0, not 2.
Option C:
Let's analyze option C: . To determine if this is equal to g(x), we need to manipulate the function f(x) = 4^x to match this expression.
We can rewrite f(x) = 4^x as f(x) = 4^x - 0. However, this is not equivalent to option C, since the constant term is 0, not -2.
Option D:
Let's analyze option D: . To determine if this is equal to g(x), we need to manipulate the function f(x) = 4^x to match this expression.
We can rewrite f(x) = 4^x as f(x) = 4^(x+2-2). Using the properties of exponents, we can simplify this expression to f(x) = 4^(x+2) / 4^2.
Since 4^2 = 16, we can rewrite f(x) = 4^(x+2) / 16. This is not equivalent to option D, since the expression is divided by 16, not multiplied by 16.
Conclusion
Based on our analysis, we can see that option A: is the correct answer. This is because we can manipulate the function f(x) = 4^x to match this expression, with a constant factor of 16.
Therefore, the correct answer is:
A.

Introduction
In our previous article, we explored how to find the value of g(x) given the function f(x) = 4^x. We analyzed four different options and determined that option A: is the correct answer.
In this article, we will provide a Q&A section to help clarify any questions or concerns you may have about the function g(x).
Q: What is the relationship between f(x) and g(x)?
A: The function g(x) is a transformation of the function f(x) = 4^x. Specifically, g(x) is equivalent to f(x-2).
Q: How do I manipulate the function f(x) to match g(x)?
A: To manipulate the function f(x) to match g(x), you can use algebraic operations such as addition, subtraction, multiplication, and division. In this case, we can rewrite f(x) = 4^x as f(x) = 4^(x-2+2) and simplify it to f(x) = 4^(x-2) * 4^2.
Q: What is the significance of the constant factor 16 in option A?
A: The constant factor 16 is not part of the function g(x). It is simply a result of the manipulation of the function f(x) to match g(x). In other words, g(x) = 4^(x-2) is equivalent to f(x) = 16 * 4^(x-2).
Q: Can I use other algebraic operations to manipulate the function f(x)?
A: Yes, you can use other algebraic operations to manipulate the function f(x). However, you must ensure that the resulting expression is equivalent to g(x).
Q: How do I determine if an expression is equivalent to g(x)?
A: To determine if an expression is equivalent to g(x), you can use the following steps:
- Rewrite the expression in terms of the function f(x) = 4^x.
- Simplify the expression using algebraic operations.
- Compare the resulting expression to g(x).
Q: Can I use other functions to find g(x)?
A: Yes, you can use other functions to find g(x). However, you must ensure that the resulting expression is equivalent to g(x).
