(a) Determine the *y-*values for a typical set of *x*-values and write them in a table.

x |
-2 | -1 | 0 | 1 | 2 | 3 |

y |
-6 | -2 | 0 | 0 | -2 | -6 |

(b) Since `y = 0` for both `x = 0` and `x = 1`, check what happens in between.

That is, for `x=1/2,` we find that `y=1/4`.

Graph of `y=x-x^2`, a parabola.

Note the curve continues beyond what is shown in the graph. This is just a general question and there are no practical limits for either the *x*- or *y*-values.
