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.)
function A: (0, -4), (1,-2), (0,2), (2,3)
function B: (0,3), (4,-9), (8,-21)
function C: y = x + 5
