Work Step by Step
To graph the given equation, perform the following steps: (1) Create a table of values by assigning $x=-3, -2 , -1, 0, 1, 2, 3$ and then solving for the corresponding y-value of each one. (Refer to the attached image below for the table of values). (2) Plot each ordered pair from the table of values, and then connect the points using a curve to form a parabola. (Refer to the attached image in the answer part above).
