Solution
Solution Steps
Step 1: Find the x-intercepts
The x-intercepts are the points where the graph crosses the x-axis. These occur at x = -2 and x = 1. As ordered pairs, these are (-2, 0) and (1, 0).
Step 2: Find the y-intercept
The y-intercept is the point where the graph crosses the y-axis. This occurs at y = 2. As an ordered pair, this is (0, 2).
Step 3: Find the domain
The domain is the set of all possible x-values. The graph extends from x = -3 to x = 3, inclusive. In interval notation, this is [-3, 3].
