We are given:
f(x) = 3x + 8
g(x) = -x³
__________________________________________________________
The Concept:
We have to find the values of f(g(3)), which means that we have to apply the function g() on 3 and apply the function f() on the value we get.
Finding f(g(3)):
Finding g(3):
g(x) = -x³
g(3) = -(3)³
g(3) = -27
Finding f(g(3)):
f(x) = 3x + 8
f(g(3)) = 3(g(3)) + 8
f(g(3)) = 3(-27) + 8
f(g(3)) = -81 + 8
f(g(3)) = -73
Hence, f(g(3)) = -73
