Which expression represents the composition [g o f o h](x) for the functions below? f(x) = 5x – 4 g(x) = 5x3 h(x) = 3x 5(15x – 4)3 (75x – 20)3 5(5x – 4)3 675x3 – 4

(A) 5(15x - 4)³

Step-by-step explanation:

When performing compositions, start at the end and work your way to the beginning. For g(f(h(x))), conduct the operations in the following order:

h(x) = 3x

              f(x) = 5x - 4

            f(3x) = 5(3x) - 4

                    = 15x - 4

                                           g(x) = 5x³

                                  g(15x - 4) = 5(15x - 4)³
