Answer
D=[0,infinity)
R=[1,infinity)
x-intercept=none
y-intercept=1
f(4)=3
Work Step by Step
The domain starts at 0 and approaches infinity. The range starts at 1 and approaches infinity. The function does not touch the x-axis. The function touches the y-axis at 1. When x is 4 on the graph, y is 3.
