5-55.

QUALITY CONTROL, Part Three

Lots O’Dough, a wealthy customer, would like to order a variety of parabolas. However, he is feeling pressed for time and says that he will pay you *lots *of extra money if you complete his order for him. Of course you agree! He sends you sketches of each parabola that he would like to receive. Determine a possible equation for each parabola so that you can pass this information on to the Function Factory.

The

-intercepts are a good place to find factors of the quadratic equation.

There is only one

-intercept, but this is a parabola, so the equation needs to be quadratic.

Use the

-intercepts to help you write a possible equation.

Notice that this parabola opens downward.
