If f (x) = x^2 and h (x) = 2-x, then hf (-3) =

hf (-3) = - 7

Step-by-step explanation:

f (x) = x²

h (x) = 2 - x

To find hf (x), we will substitute f (x) function as x into the h (x) function.

h (x) = 2 - x

hf (x) = 2 - (x) ²

hf (x) = 2 - x²

How that we have the hf (x) function, to find hf (-3), we substitute x = - 3 into the new function.

hf (x) = 2 - x²

hf (-3) = 2 - (-3) ² = 2 - 9 = - 7
