Unformatted text preview: For example, in the following graph, the solutions to the quadratic equation are x = 3 and x = 2, since the graph crosses the xaxis at (3, 0) and (2, 0). If the graph never crosses the xaxis, such as in the following case, then the equation doesn’t have any realnumber solutions: Finally, if the graph only touches the xaxis at one place, the equation has only one solution, such as it happens with the graph of y = (x + 1) 2 , shown next.
