AN 6.1, 6.2

Complete the graph. You have the vertex (middle) of the graph. Create points to make the graph symmetric.

Y-intercept (only 1)

X-intercepts (there are 2)

Where does the graph have a positive slope?

What should the new price be for maximum profit? (What toy price??)

What is the minimum price of a toy that will produce profit? At what number does the graph begin to have a profit??

Estimate the value of P(10).

(when the x=10 what does y=??)

How much should they sell for if they want a profit of $137? (two answers- read from the graph)

Domain (between what x values will there be a profit?)

Write the equation using the solutions.

Which are TRUE?

Use the discriminat to determine which have two real solutions.
