Answer
The domain of the function is $\left( -2,2 \right)$ and its range is $\left[ 0,\left. \infty \right) \right.$.
Work Step by Step
The domain is the span of the x-axis for which function is defined and the range is the span of the y-axis for which the function is defined.
From the graph, observe that the function is only defined for $\left( -2,2 \right)$ on the x-axis and $\left[ 0,\left. \infty \right) \right.$ on the y-axis.
