Which cube root function is always decreasing as x increases? fx=cube root ofx-8 fx=cube root ofx-5 fx=cube root of-5-x fx=-cube root ofx+5

Accepted Solution

A:
A Write properties of function: x intercept/zero: x = 8increasing interval: nodecreasing interval: (-\infty, \infty)B Write properties of function: x intercept/zero: x = 125increasing interval: nodecreasing interval: (-\infty, \infty)C Write properties of function: x intercept/zero: x = 5increasing interval: nodecreasing interval: (-\infty, \infty)D Write properties of function: x intercept/zero: x = 125increasing interval: nodecreasing interval: (-\infty, \infty)
