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