D=(-infinity, infinity) R=[1,infinity) x-intercepts=none y-intercept=1 f(-1)=2 f(3)=4
Work Step by Step
The domain is infinite in both directions. The range starts at 1 and goes infinitely up. The function does not touch the x-axis. The function touches the y-axis at 1. When x is -1 on the graph, y is 2. When x is 3 on the graph, y is 4.
