Answer:


f(g(x)) =
√(8x - 4)

Explanation:


f(x) = √(x + 8)


g(x) = 8x - 12


f(g(x)) is the combination of the functions
f(x) and
g(x) such that
g(x) is the input to the function
f(x) .

This means, we have to replace the original input of
f(x), which is
x, with the function
g(x).


f(g(x)) =
f(8x - 12)


√(8x - 12 + 8)


√(8x - 4)
