Question

I don’t know how to do this. And need help knowing how to solve this!

Answer 1

Answer:

$f(-1)\text{ = -16}$

Explanation:

Here, we want to get the value of the given function

The x value here is -1

-1 falls under the domain of the first piece-wise function

That means we are going to use the first function

Thus, we have it that:

$\begin{gathered} f(-1)\text{ = 8\lparen-1\rparen-8} \\ f(-1)\text{ = -8-8 = -16} \end{gathered}$
