1. 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}

2. 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.
