Question

Please help me. i don’t understand how to interpret the (f o g)(x) And (g o f)(x)

Answer 1

fog functions are basically saying f(g(x)).

So (f o g)(x) = f(g(x)).

This is also true for gof functions.

(g o f)(x) = g(f(x)).

All we do for these problems is plug in g(x) into the x value in the f(x) equation.
