Question

Refer to the following graph which shows the number f(t) of housing starts for single-family homes in a country each year from 2000 through 2014

(t = 0

represents 2000, and f(t) is the number of housing starts in year t in thousands of units).

A graph has a horizontal t-axis with values from 0 to 14 and a vertical f(t)-axis with values from 0 to 2200. The graph contains a series of 15 points connected by line segments. The segments and the approximate points they connect are as follows.

The segments start at (0, 1400),
go up and right to (1, 1500),
go up and right to (2, 1600),
go up and right to (3, 1700),
go up and right to (4, 1800),
go up and right to (5, 1900),
go down and right to (6, 1700),
go down and right to (7, 1200),
go down and right to (8, 800),
go down and right to (9, 600),
go up and right to (10, 700),
go down and right to (11, 600),
go up and right to (12, 700),
go up and right to (13, 800),
and go right to stop at (14, 800).
