Test 2 Section 5 - #7 (page 465)

If you have a graphing calculator, this one is probably easiest to do using Plug-In. First, plug in anything you want for a... let's go with a=3. Now graph that equation: y=3x²+2. Next graph the SECOND equation (y=x²+2) and compare the two graphs. You'll see that the second graph is wider than the first, so the answer is (B).
