Question

Evaluate a function below round to the fourth decimal places if necessary.

Answer 1

In order to evaluate the function, we need to substitute the value -1 into the place of x, that is,

`f(-1)=-4^(2(-1)+3)`

which gives

`\begin{gathered} f(-1)=-4^(-2+3) \\ f(-1)=-4^1 \end{gathered}`

Therefore, the answer is:

`f(-1)=-4`
