Question

Y=20x2 - 40 Could you draft the chart?

Answer 1

Given:

The equation is:

$y=20x^2-40$

To draw:

The graph of the given equation.

Solution:

We have,

$y=20x^2-40$

The table of values for the given equation is:

x :        -2                -1                0                1                2

y :       40              -20            -40             -20             40

Plot these points on a coordinate plane and connect them by a free hand curve.

The graph of the given equation is shown below.
