Answer 1

I don't have the definitions for Functions A and B — only Function C: y = x + 5. Please paste the formulas for A and B and I’ll answer each question exactly.

Meanwhile, here are general rules you can use (and a quick answer for function C alone):
- Negative rate of change (slope): any function whose slope coefficient is negative (e.g., y = -2x + 3).
- For C (y = x + 5) the slope is +1, so C does NOT have a negative rate of change.
- Smallest y-intercept: compare the constant terms; the smallest constant is the smallest y-intercept.
- For C the y-intercept is 5.
- Best to represent money earned per hour: choose a function with a positive slope (rate of earning) and typically a y-intercept of 0 (starts at $0 before working). If you must have an initial bonus, a positive intercept is fine.
- Highest initial amount of money: the function with the largest y-intercept.
- For C the initial amount is $5.

Send A and B and I’ll fill in the specific answers.
