SOLUTION: Find (g o f)(3) if g(x) = 3x and f(x) = x - 3
Need help solving, I see the formula, but don't get it.
(g o f)(3) = g(f(3)).
We need to find f(3) first.
f(x) = x - 3

Question 544555: Find (g o f)(3) if g(x) = 3x and f(x) = x - 3
Need help solving, I see the formula, but don't get it.
(g o f)(3) = g(f(3)).
We need to find f(3) first.
f(x) = x - 3
f(3) = 3 - 3
f(3) = 0
We now know that f(3) = 0.
g(f(3)) = 3x
g(f(3)) = 3(0)
g(f(3)) = 0
