Please upload the definition of the functions h(x) and f(x) so we can use them to answer the question.

We are asked to evaluate the expression

h(8) - 2 * f(3)'so we first evaluate f(3) and h(8) given the functional expressions of f an h:

f(x) = - x^2 + 8x - 11

f(3) = - 3^2 + 8 (3) - 11 = 4

h(x) = - x - 7

h(8) = - 8 - 7 = -15

Now we use these values in the requested expression:

h(8) - 2 * f(3) = - 15 - 2 * (4) = -15 - 8 = - 23
