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

Solution:

The exponent of a number shows how many times the number is multiplied by itself.

The given function is

ƒ(x) = 4^2x - 100

We have to determine the value when x = 2

f(2) = 4²⁽²⁾ - 100

f(2) = 4⁴ - 100

By further calculation

f(2) = 256 - 100

f(2) = 156

Therefore, the value is 156.

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

Summary:

The value for ƒ(x) = 4^2x - 100 when x = 2 is 156.
