ESTIMATING SOLUTIONS BY GRAPHINGThe solutions of a quadratic equation in one variable x can be estimated by graphing. Use the following steps:STEP 1 Write the equation in the standard for ax2 +bx + c = 0STEP 2 Sketch the graph of the related quadratic functiony = ax2 +bx + c STEP 3 Estimate the values of the x-intercepts, if any.
The solutions, or roots, of ax2 +bx + c = 0 are the x-intercepts of the graph.
