    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
