Work Step by Step
To graph the given parabola, perform the following steps:
(1) Create a table of values by assigning $x=-8, -4, -2, 0, 4$ then solving for the corresponding value of $y$ of each one.
(refer to the attached image below)
(2) Plot each ordered pair of the table of values then connect them using a smooth curve to form a U-shaped graph.
(refer to the attached image in the answer part above)
