Given:

h(x) = x - 7

g(x) = x^2

Determine (g o h)(5)

Solution:

The given condition is a composition of a function where as we substitute the value of h to the x of g, and the x of h will also be substituted by the value 5. 

(g o h)(5) = (5 - 7)^2

(g o h)(5) = (5 - 7)^2

(g o h)(5) = (-2)^2

(g o h)(5) = 4

Final answer:

(g o h)(5) = 4
