Question 313360: would you mind explaining what to do in the event that the lines in the graph of a quadratic equation are straight? (instead of curving like it does now, it goes striaght, stops, then "bounces" off)

Quadratics are never straight although they may appear so.
If it's straight, it's not a quadratic.
Here's an example of 3 quadratics : y=10x%5E2, y=100x%5E2, and y=1000x%5E2
+graph%28+300%2C+300%2C+-10%2C+10%2C+-10%2C+10%2C+1000x%5E2%2C100x%5E2%2C10x%5E2%29+

But upon closer examination, they do look like quadratics.
+graph%28+300%2C+300%2C+-1%2C+1%2C+-10%2C+10%2C+1000x%5E2%2C100x%5E2%2C10x%5E2%29+

Do you have examples of what you mean?
