Function A: the graph goes through the points -4, 0, -2, 1, 0, 2, and 2, 3. Function B: x: 0, 4, 8 y: 3 ,-9 ,-21 Function C: y=x+5
Which function has a negative rate of change (slope)?
Which function has the smallest y-intercept?
Which function would you want to represent your money earned per hour?
Which function would give you the highest initial amount of money?
Function A has a negative rate of change (slope) because it is decreasing as x increases.
Function B has the smallest y-intercept at -21.
Function C would be the best representation for money earned per hour because it has a constant rate of change (slope).
Function B would give you the highest initial amount of money because it has the highest y-value at x=0, which is 3.
