Module 3
Lab 3.1
1a. y=20,000-2,800x
1b. y=20,000-2,800(x)
Y=20000-14000=6000
1c. y= Car Value x= Vehicle Age
1d.
2a. Plan A
Plan B
45 = 15 + .10x
-15 = -15 + .10x
30 = .10x
/.10 = /.10
300 = x
2b. After 300

1. y = 0.022(7)^2 + 0.25
y = 1.328
1b) 14=0.022x^2 + 0.25
Year 2025
1c) (0,0.25) Turning point of 2000.
2. Let x = the number of computers that costs $30 to upgrade.
Then the number of others computers is 200 - x.
30*x + 45*(200-x) = 7125.
solve this equa

1. You could use a vertical line test to test whether the graph is a function or not. If the
vertical line intersects more than 1 point on the graph, it doesnt define y as a function of
x.
