Answer: 22
Work Shown
Plug x = -2 into h(x).
h(x) = x^2 + 5
h(-2) = (-2)^2 + 5
h(-2) = 4 + 5
h(-2) = 9
Don't forget to square the negative sign along with the value itself.
Plug x = 3 into f(x)
f(x) = 2x+7
f(3) = 2*3 + 7
f(3) = 6 + 7
f(3) = 13
Then finally,
h(-2) + f(3) = 9 + 13 = 22 is the final answer
GeoGebra or Desmos can be used to verify.
