Let x meters be the height of the building.
Answer:
:)
Step-by-step explanation:
There are several ways to do this. The first, which I personally think is the quickest way without having to do too much math or rearranging the equation is to simply pick random points for x and solve for y.
For instance, you might try -2 for x.
- ( - 2)^2 - 4 ( - 2) - 3
= - 4 + 8 - 3
= 1
So one of your points would be (-2, 1)
Then you might choose, say, -3 for x. And after that, -1 for x. If you want to graph even more points after those (the more points, the more accurate your graph), choose -4 and 0 for x. Simply put it into the equation and find y. Then graph.
