3.12 Intersection of Graphs
Algebraically – Get all terms on one side and solve. The easiest thing to do is to plug in 1 and -1 (or 2 and -2) if you get the same y, then it’s Even. If you get the opposite y, then it’s Odd. If you get different y’s, then it’s Neither. Graphically – Graph each function separately and look for the points where they cross.

Ex. 1 f(x) = 2x + 5, g(x) = 3x - 2 Graphically Algebraically

Ex. 2 f(x) = 2x2 - 3, g(x) = x2 – 2x Graphically Algebraically
