Chapter 4 - An Introduction to Functions - 4-4 Graphing a Function Rule - Practice and Problem-Solving Exercises - Page 258: 36

Function B

The graph shows a y-intercept of -1 so we can eliminate choices A and D because they both have y-intercept of +1. We can also eliminate choice C because it has an absolute value function however the graph shows a linear function. Therefore by process of elimination, we get the answer to be function B.
