Question

Find the value by evaluating the function. Do not include any spaces in your answer.

Answer 1

SOLUTION

We want to find the value of the function by evaluating it;

$\begin{gathered} w(n)=n^2-1 \\ w(-4) \end{gathered}$

We do this by inserting -4 into the equation;

$\begin{gathered} w(-4)=(-4)^2-1 \\ =16-1 \\ =15 \end{gathered}$

Therefore, the answer is 15
