Which pair of functions are inverses of each other? O A f(x) = f +4 and g(x) = 3x - 4
O B. f(x) = 2x - 9 and g(x) = 57°
O c f(a) = ¥ and g(x) = 5x3
O D. f(x) = 2 - 6 and g(x) =
2+6
2

You are solving for x here. To solve for x you need to isolate it onto one side of the equation. First multiply -4 into (-6x - 3) to get 24x + 12. Now that you have a simplified equation on both sides, subtract 12 from both sides to get 24x = 0. Because anything multiplied by 0 equals 0, x = 0.
