Answer:

f(-5) = -33

Step-by-step explanation:

f(x) = {-x^2+2x+2 if  x ≤  - 5

        {-3/4x+3 if   x > 1

find what f(-5) = ​

If x=-5, we use the first equation

f(-5) =  -x^2+2x+2  since it has the equal to part

       = - (-5)^2 +2(-5) +2

        =  -25 -10+2

        = -35+2

         =-33
