Question

When finding the composition of f (g (x) )substitute f (x) for the x in g (x)multiply f (x) by g (x)substitute g (x) for the x in f (x)

Answer 1

Okay, here we have this:

Considering that the composition of function is formed by taking the outputs of one function and converting them into the inputs of another function. We obtain that, f(g(x)), consists of taking the result obtained by evaluating g (x) and replacing it by x in f (x). Then the correct answer is the third option.
