Question

The plecewise linear function y = f(x) is shown graphed. 1. Evaluate each of the following based on the graph: f(3) =

Answer 1

The graph shows the linear function y=f(x)

1. For f(4) you have to look the value of y when x=4

In this graph, when x=4 → y=1

2. f(-3) look for the value of y when x=-3

In the graph, when x=-3 → y=-5
