Question

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

Answer 1

Step-by-step 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}`
