Simply providing you with the answer would not help you understand how these functions operate. I suggest graphing each of these functions on a calculator or by hand as a functions of **x** and notice the pattern of behavior as **x** increases.

For example

Cubic function can be graphed as x^{3}

Cube root function can be graphed as x^{1/3} and so on.

You can manually draw these functions. To do so start off by plugging in small values for x and increasing the values to see the pattern of behavior.

For example

f(x) = x^{3}

f(1) = 1^{3} = 1

f(10) = 10^{3} = 1,000

f(100) = 100^{3} = 1,000,000
