The Food Stamp Program is Americas first line of defense aga

The Food Stamp Program is America\'s first line of defense against hunger for millions of families. Over half of all participants, am children, one out of six is a low-income older adult. The function, f(x), models the number of people, in millions, receiving food stamps x years after 1990. Use the graph of f(x) given above the answers to the following questions. How many million people received food stamps in the year 2004? In which year(s) did 22 million people receive food stamps?

Solution

a) 10 million

draw a vertical line at x=14 (because 2004 = 1990+14 and see where it intersects with the curve)

b)

year 1992 , 2000

draw a horizontal line at y=22 and see where it intersects with the curve

you would see, it intersects at x = 2 , 10

therefore, 1990 +2 , 1990+10

1992 , 2000
