f (h (x)) = 2x - 21

Step-by-step explanation:

f (x) = x^3 - 6

h (x) = / sqrt[3]{2x-15}

WE need to find f (h (x)), use composition of functions

Plug in h (x)

f (h (x)) = f (/sqrt[3]{2x-15})

Now we plug in f (x) in f (x)

f (h (x)) = f (/sqrt[3]{2x-15}) = (/sqrt[3]{2x-15}) ^3 - 6

cube and cube root will get cancelled

f (h (x)) = 2x-15 - 6 = 2 x-21
