To find the domain of graph, we notice at the point on the left and the right.

Domain is the set of all x-values, so we perceive in a horizontal line or x-axis.

The first point on left is at x = -1 and the second point on the right is at x = 1.

Since the points are opened and therefore, the Inequality signs can only be > or <.

Therefore, the domain is -1 < x < 1

To find the range, similar to domain but we perceive vertical line or y-axis. Range is the set of all y-values.

We notice that the minimum point is -1 or y = - 1 and maximum point at 1 or y = 1.

Therefore, the range is -1 < y < 1
