Question

Perform the requested operation or operations. f(x) = 5x + 15, g(x) = 3x - 1

Answer 1

Are you working on composite function? Are you trying to find (f(g(x))) or (g(f(x)))?

Answer 2

If you are doing (f(g(x))), then you would take the g(x) function and substitute that in to the f(x) equation where you see x. So it would be f(x) = 5(3x-1)+15.
For (g(f(x))), you would do the opposite. You would substitute the f(x) function into the g(x) function where you have an x. So you would have g(x) = 3(5x+15)-1.
