Question

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

Answer 1

Answer: f(2)=156

Step-by-step 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:

$f(2)=4^{2*2}-100\\f(2)=4^{4}-100\\f(2)=156$

Answer 2

Answer:

The value of f(2) = 156

Step-by-step 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
