find f * g if f(x) = x^2-7 and g(x) = 2x+4

do i combine the two equations?

It depends.

if this is multiplication of functions.

If it is composition of functions:

It is this:
(f \circ g)(x) = f(g(x)) = f(2x + 4) = (2x + 4)^2 - 7
but i am a bit confused

I think aikenfan asked for



Which is the same result of Dan
