(a) Using a viewing rectangle that extends from -5 to 5 in both the x- and y-directions, graph the equation . Use the graph to estimate the roots of the equation How do your estimates compare to the actual values determined in Example 5?

(b) Using the viewing rectangle specified in part (a), graph the equation On the basis of the graph, make a statement about the roots of the equation Then solve the equation algebraically to confirm your statement.
