Three functions of the form ()=+f of . open x close equals eh , x squared , plus b x are graphed for =eh equals 2 and different values of b. A. What do the graphs have in common? In what ways do they differ?

B. What do you notice about the x‑intercepts of each graph? What do you notice about the y‑intercepts of each graph?

C. Look for Relationships Look at the ratio b over eh for each function and compare it to its graph. What do you notice?
