RECALL: (1) The x-intercept is the x-coordinate of the point where the graph crosses/touches the x-axis. (2) The y-intercept is the y-coordinate of the point where the graph crosses/touches the y-axis. Notice that the graph crosses: (a) the x-axis at $(-1, 0)$ and $(1, 0)$; and (b) the y-axis at $(0, 1)$. This means that the graph has: (a) x-intercept/s = -1 and 1 (b) y-intercept/s = 1
