The table shows the percentage of people living below the poverty line in one U.S.
city in the years 2000 through 2003.
Percentage of people living
below poverty line
11.7
Year
2000
2001

2002
13.7
2003
13.8
The data in the table can be written as ordered pairs (x, y) where x is the number of
years after 2000 and y is the percentage of people living below the poverty line in
that year. Use the data for 2000, 2002, and 2003 to find the quadratic function
+ bx +c that models the percentage, y, of people in this city living below the
y= ax2
poverty line x years after 2000.
[Hint: Find a, b, and c by substituting each of three ordered pairs into the function
and writing and solving a system of linear equations in three variables.]
Oy = -0.3x2 + 1.6x + 11.7
y = -0.4x2 + 1.9x + 11.7
Oy = -0.4x2 + 1.8x + 11.7
y = -0.2x2 + 1.4x + 11.7
