Find each of the function below, indicate whether the function in onto, on-to-one neither or both. If the function is not onto or nor one-to-one, give an example showing why . H;Z Z. h(x)=x^3

Notice that this function passes BOTH a vertical line test and a horizontal line test.

$y_1=y_2=>x_1^3=x_2^3$

$=>(x_1-x_2)(x_1^2+x_1x_2+x_2^2)=0$

$=>x_1=x_2, \text{where} \,x_1,x_2\in \R$

The function $g(x)=x^3$ is one-to-one.

$\forall y\in \R \ \exist x=\sqrt[3]{y}$ ​such that $y=x^3.$

The function $g(x)=x^3$ is onto.

Therefore the function $g(x)=x^3$ is bijection.
