Question

What is the value for f(x)=4^2x-100 when x=2

Answer 1

The value of f(2) = 156

Explanation:

The given expression is f(x)=4^2x-100

To find f(2)

when x=2 means we have to find the value of f(2)

Substituting the value of x as 2

f(x)=4^2x-100

f(2) = 4^(2*2) - 100 (Substitute the value of x = 2)

f(2) = 4^4 - 100

f(2) = 4*4*4*4 - 100

f(2) = 256 - 100

f(2) = 156

Therefore the correct answer is f(2) = 156

Answer 2

Answer: f(2)=156

Explanation:

To solve this problem you must apply the proccedure shown below:

1. You have the following function:

`f(x)=4^(2x)-100`

2. Then, you must substitute x=2 into the function given in the exercise. Therefore, you have the following result:

`f(2)=4^(2*2)-100\\f(2)=4^(4)-100\\f(2)=156`
