Show answer Solving equations with quadratic graphs Graphs of quadratic functions can be used to solve equations. Example Draw the graph of y = 2 x 2 + 2 x 4 for values of –3 to 2.

Step 5 – Plot a graph using the values you have found. It should go from – 2 to 2 on the x axis, and from 0 to 4 on the y axis. Step 6 – Plot the points from your table on the graph.
