Do you have a TI-83?

2. Allypally

No

3. OpenSessame

Ohkay...

4. OpenSessame

look at the graph and then ill explain how you can draw the parabola.

6. Allypally

Ok that equation isn't the same as mine

7. OpenSessame

I know, but i just wanted you to see sort of what it would look like...

8. Allypally

Oh ok I know how to solve it, but when I graph it it doesn't curve

9. OpenSessame

What do you mean?

10. OpenSessame

Did you do the three point thing?

11. Allypally

No

12. OpenSessame

You should do that...Find the Lowest point.

13. OpenSessame

You can get a rough idea of the graph from 2 things: 1) The coefficient of x² If it is positive, the graph will be concave up. (shaped like a 'U'). 2) Solve for x. The roots of the equation are -1 and -5 These are the two points where the parabola crosses the x axis. With this small amount of information, we can make a rough graph of the equation.
