Compare the graphs of the functions given by p(x) = (x - 1)(x - 3) and q(x) = (x + 1)(x + 3).[br][br][list=1][*]What will their x-intercepts be?[/*][*]Where will the x-coordinate of the vertex of each graph be?[/*][*]How do we find the y-coordinate of each vertex?[/*][*]The y-intercept of both graphs is (0, 3). What is another point on each graph with the same y-coordinate?”[/*][/list]
(1, 0) and (3, 0) for the graph of function p, and (-1, 0) and (-3, 0) for the graph of function q.[br]2 for the graph of p and -2 for that of q.[br]Evaluate p(2) and q(2)[br]The point 2 units to the right of the vertex of p will have same y-coordinate, so (4, 3). The point (-4, 3) is on the graph of q.
