normally I would know hoe to solve this is a number was in the place of the x but since the x is there, I'm stuck.

f(x) = 8x + 2

g(x) = x

^{2}- 8To take the composition of f and g (fog), replace the x in f(x) with g(x):

(fog)(x) = 8g(x) + 2 [f(x) = 8x + 2]

(fog)(x) = 8(x

^{2}- 8) + 2 [since g(x) = x^{2}-8](fog)(x) = 8x

^{2}- 64 + 2(fog)(x) = 8x

^{2}- 62For a primer on composition of functions, check out the following:
