A. function A
B. function B
C. function C

2. which function has the smallest y-intercept?_________
A. function A
B. function B
C. function C

3. which function would you want to represent your money earned per hour?________
A. function A
B. function B
C. function C

4. which function would give you the highest initial amount of money?__________

1 answer

1. A. function A (The slope of function A can be calculated as (3-(-4))/(2-0) = 7/2 = 3.5, which is greater than the slopes of function B and C.)

2. B. function B (The y-intercept of function A is -4, the y-intercept of function B is -9, and the y-intercept of function C is 5. -9 is smaller than -4 and 5.)

3. A. function A (Function A represents a rate of change from -4 to 3 over 2 units, which can be interpreted as earnings per hour.)

4. B. function B (The initial amount of money can be determined by looking at the y-intercept. The y-intercept of function A is -4, the y-intercept of function B is -9, and the y-intercept of function C is 5. -9 is the highest initial amount.)
