Evaluate h(3), where h = g compose f.
f(x) = cubert.(x^2 − 9) g(x) = 8x^3 + 9

  • Math -

    g(x) = 8x³+9
    f(x) = (x²-9)^(1/3)

    h(x)
    = g o f
    = g(f(x))
    = g((x²-9)^(1/3)
    = 8((x²-9)^(1/3))³+9
    = 8(x²-9)+9

    h(3)
    = 8(3²-9)+9
    = 8(0)+9
    = 9

    [CUBERT(2x + 9)]=3
