Multiply by 3, raise to the third power, and then add 20. (a) Write a function of x that performs the operations described above. y = 9x3+20 (b) Find the inverse of the function from part (a). x - x = 3 20 9 Find the inverse function, g(y), of h(x) = 2 x- 10. g(y) x+10 2 Find the inverse function, g(y), of h(x) = x+9. g(y) = x 9 Find the inverse function, g(y), of h(x) = 3x + 11 g(y) x- 11 3
