Question

How do you graph `y = x^2 + 2x` using a table of values?

Answer 1

graph{x^2+2x [-2, -1, 0, 1, 2]}

(X, Y)
(-2, 0)
(-1, -1)
(0, 0)
(1, 3)
(2, 8)

Explanation:

So let plug in a few values, you should use -2, -1, 0, 1, 2 for your x values.

So let plug in a couple of values.

`(-2)^2` + 2(-2)
4 + -4 = 0

So just keep plugging in values of what you need then graph.
