ANSWER
y=x
y=x³
EXPLANATION
A function, f(x) has an inverse if and only if

Thus, the function is one to one.
For y=x or


Hence this function has an inverse.
For the function y=x² or f(x)=x².

This function has no inverse on the entire real numbers.
For the function y=x³ or f(x)=x³

This function also has an inverse.
For y=x⁴ or f(x) =x⁴

This function has no inverse over the entire real numbers.
