(a) x-intercept = -1 (b) no y-intercept

Work Step by Step

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 the x-axis at $(-1, 0)$ but does not cross nor touch the y-axis. This means that the graph has: (a) x-intercept/s = -1 (b) no y-intercept
