The function has a domain of all real numbers . True

The cube root of real number is also real. The negative sign is outside he radical so it cannot result to an imaginary number.

The function is a reflection of y =³√x . True

The function is always increasing. False

When getting the cube root of a number the result is alway smaller. So the domain of the function should be decreasing not increasing.

The function has a range of {y|– < y < } . False

The function passes through the point (3, –27) . False

When this values are substituted it the function they don't satisfy it.
