Solve by Graphing
Lesson:
- Method 1: the equation equals zero, graph y= and find the zeros of the function. The zeros are the answers to the equation.
- Method 2: the equation has a left and a right side, graph one side in y1 and the other side of the equation in y2. Find where the graphs intersect. The x-values of the intersection points are the answers to the equation.
