Question

Graph. h(x) = − 2x² Plot five points on the graph of the function: one point with x = 0, two points with negative x-values, and two points with positive x-values. ​

Answer 1

see below and attached

Explanation:

The easiest way to do this is to make an x, h(x) table (see picture), and then graph those points as (x,y) coordinates (see graph).

PS: What do you notice about the coordinates (-1,-2) & (1,-2) and (-2,-8) & (2,-8)?

Also, What do you notice when you compare the vertex (0,0) to either (-1,-2) or (1,-2)?
