Question

For the function f(x) = 4²-¹f(4)=f(8) =11114-1 calculate the following function values:

Answer 1

EXPLANATION:

Given;

$f(x)=4^{x-1}$

Required;

We are required to calculate the value of the function at the input levels indicated.

Step-by-step solution;

To solve the problem, we shall evaluate the function by taking the value of the function at the value given (in place of x).

$\begin{gathered} (i) \\ f(4)=4^{(4-1)} \end{gathered}$$f(4)=4^3$$f(4)=64$

For the second part;

$f(8)=4^{(8-1)}$$f(8)=4^7$$f(8)=16,384$

Therefore, the function is valued as follows;

ANSWER:

$\begin{gathered} f(4)=64 \\ f(8)=16384 \end{gathered}$
