1. Fungsi f(x) = 3x-1 dan g(x) = x+2/x-1. Jika invers dari fungsi g=f adalah ( g o f )^-1 (x). Maka tentukanlah (g o f)^-1 (x)

2. f(x) = 3x-10 / 2x-5, x ≠ 5/2 dan g(x) = x+2. Jika h(x) = (fog) (x) dan h^-1 adalah fungsi invers dari h, maka tentukan lah h^-1 (x)​

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

-2 is the right
