Question

Please help :)

Given f(x) = -x² + 9x − 17, find f(−5)

Answer 1

f(x)= 3

Explanation:

If f(x) is equal to -
`x^(2)`+9x-17 and f(-5)

You will substitute -5 where you see all the x's

-(-5)
`^(2)`+9(-5)-17

That will equal to

-25+45-17

Combine all the like terms

This will lead you to answer 3

So, f(x) =3

Answer 2

Answer: -87

Step-by-step explanation: -(−5)² + 9(−5) − 17 =

-25 - 45 - 17 = -87
