The graph represents f(x) = .[x] + 3

what is f(−2.2)?

a. -2
b. 0
c. 1
d. 2

The correct answer is:

C. 1

Explanation:

Using the graph for f(-2.2), we go to -2.2 on the x-axis.  This will lie between -2 and -3.  We then go up to see where it we "meet" the graph.  This happens at y=1, so that is our answer.
