Answer #1

Answer: please see the attached file.

Explanation: For plotting the graph, first find the ordered pairs for the equation y=2x2 . the ordered pair can be found by varrying the value of x and finding the corresponding values of y. So, (x, y) will be the ordered pairs.

x-value:0, 1, -1, 2, -2, 3, -3, 4, -4, etc.

y-value:0, 2, 2, 8, 8, 18, 18, 32, 32, etc.

So, the ordered pairs are (0, 0), (1, 2), (-1, 2), (2, 8), (-2, 8), (3, 18), (-3, 18), (4, 32), (-4, 32) .... etc.

The plot of the ordered pairs will be like this
