The applet below has the graph of y=a(x-p)(x-q). You can change the value of a, p, and q, by moving the sliders.
Move the sliders a, p, and q, and see how the graph changes. Then, answer the questions below in your notebook.

**Question 1:**How does "a" affect the graph of y=a(x-p)(x-q)?

**Question 2:**How does "p" and "q" affect the graph of y=a(x-p)(x-q)?

**Question 3:**What are the x-intercepts of y=a(x-p)(x-q)?

**Question 4:**What are the x-intercepts of the following: a) y=2(x-3)(x+1) b) y=-(x+2)(x+8) c) y=3(x+2)^2 d) y=8x(x-4) e) y=x^2-2x-3
