For the given functions f and g , find the indicated composition. f(x) = 3x + 9, g(x) = 5x - 1 (fg)(x) A) 15x + 12 B) 15x + 8 C) 15x + 6 D) 15x + 44
ok so another way to look at this is f(g(x)) Our x variables get replaced with g(x) f(5x-1) So you replace your x variables in f(x) with 5x-1
OH thats right I was trying to disturbte them
