Question

f(x) = x^2 - 9x + 2 evaluate f(-2)

Answer 1

ANSWER

f(-2) = 24

EXPLANATION

We are given the function:

$f(x)=x^2-9x+2$

To find f(-2), we have to subtitute -2 for x in the function. That is:

$\begin{gathered} f(-2)=(-2)^2-9(-2)+2 \\ f(-2)=4+18+2 \\ f(-2)=24 \end{gathered}$

That is the answer.
