Best ResponseYou've already chosen the best response.2rearrange equation to solve for x switch x and y to get the inverse function Let y = 1/(9x  2) rearrange to solve for x 9x  2 = 1/y 9x = 1/y + 2 x = 1/(9y) + 2/9 switch x and y y = 1/(9x) + 2/9 f⁻¹(x) = 1/(9x) + 2/9 ===== Let y = (1/9)x  2. (1/9)x = y + 2 x = 9y + 18 g(x) = 9x + 18 < Your final answer
