Question

How do you graph `y = x^2 -12` by plotting points?

Answer 1

Make a table from different `x-`values, say from `-5to+5`

Explanation:

You will get:
`(-5,13),(-4,4),(-3,-3),(-2,-8),(-1,-11),(0,-12),(1,-11),(2,-8),(3,-3),(4,4),(5,13)`

If you plot these on graphing or grid paper, you may draw a curve to connect them.
graph{x^2-12 [-16.39, 15.65, -13.05, 2.99]}
