Consider the equation $y=x^2$y=x2.
Complete the following table of values.
$x$x | $-3$−3 | $-2$−2 | $-1$−1 | $0$0 | $1$1 | $2$2 | $3$3 |
---|---|---|---|---|---|---|---|
$y$y | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |
Plot the points in the table of values.
Hence plot the curve.
Are the $y$y-values ever negative?
No
Yes

$2$2
$3$3
$1$1
Consider the equation $y=-x^2$y=−x2.
Consider the equation $y=3x^2$y=3x2.
Consider the equation $y=-2x^2$y=−2x2.
