A.6.11.2 Comparing Two Graphs
- Katie Akesson
f(x) = x(x +4) g(x) = x(x - 4) Complete the table of values for each function below. Then, determine the x-intercepts and vertex of each graph. Explain how you know.
Plot the points from the tables on the same coordinate plane. (Consider using different colors or markings for each set of points so you can tell them apart.) Then, make a couple of observations about how the two graphs compare.
Compare the graphs of the functions given by p(x) = (x - 1)(x - 3) and q(x) = (x + 1)(x + 3).
