Question

Evaluate the function.
F(x) = -x^2+9x-17
Find F (-5)

Answer 1

⇒F(-5) just simply means that in the function F in the place of x you have to plug in -5 and simplify if possible.

`f(-5)= -(-5)^(2) +9(-5)-17\\f(-5)=-(25)-45-17\\f(-5)=-25-45-17\\f(-5)=-70-17\\f(-5)=-87`

the answer to f(-5) is -87

GOODLUCK!!
