Function A points: (0, -4), (1, -2), (0,2) and (3,2)
Function B: x: 0, 4, 8 y: 3, -9, -21
Function C: y= x+5
Questions:
1. Which function has a negative rate of change (slope)?
2. Which function has the smallest y-intercept?
3. Which function would you want to represent your money earned per hour?
4. Which function would give you the highest initial amount of money?
Answers:
1. Function B has a negative rate of change because as x increases, y decreases.
2. Function B has the smallest y-intercept, which is 3.
3. Function C (y = x + 5) would represent money earned per hour because the equation is linear and the hourly wage would be represented by the slope of 1.
4. Function A would give the highest initial amount of money because the point with the highest y-value is (3,2), which means the initial amount is 2.
