# How do you find the domain and range for y=x^3?

Oct 15, 2017

$D$: All real x

$R$: All real y

#### Explanation:

You can best do this by graphing the equation and seeing the domain and range through that:

graph{x^3 [-101.4, 101.4, -50.7, 50.7]}

As you can see, the graph has no asymptotes and extends infinitely both across the x- and y-axis.

Therefore:

$D$: All real x

$R$: All real y
