# What is the domain and range of y=x^3?

The domain and range are all real numbers $\mathbb{R}$
The domain is the subset of $\mathbb{R}$ for which the function can be calculated. It is a polynomial, therefore the domain is not limited.
The range is also $\mathbb{R}$. The end behaviour can be a hint. If $x$ goes to $- \infty$ $y$ also goes to $- \infty$ and if $x$ goes to $+ \infty$ $y$ also rises to $+ \infty$
