The graph on the left represents the one solution to the equation [math] \sqrt{x} = 2x - 6 [/math], with [math] f(x) = \sqrt{x} [/math] and [math] g(x) = 2 x - 6 [/math]. [br][br]The graph on the right represents the two solutions to the equation [math] ({\sqrt{x}})^2 = ({2x - 6})^2 [/math]. [br][br]By checking the box labeled "See where the extra solution [math]{r_2}[/math]comes from!", you can see the extraneous solution.
