Warm up Find f(-3). -8 Find g(0). Given r(x) = 2x – 1, evaluate the domain {0, 1, 2, 3}. What is the range of r(x)? -8 2 Range: {-1, 1, 3, 5}

Points of Intersection Graphically and Algebraically 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.
