To find the xintercept(s), set y = 0, and solve for x: 0  3/2 = x Thus the xintercept would be (3/2,0), but this is outside the given domain. To find the yintercept, set x = 0, and solve for y: y  3/2 = 0 y = 3/2 Thus, the yintercept is (0,3/2). The second equation reduces to y = 3, which has no xintercept, and the yintercept is (0,3).
