Answer 15

`Scenario 2 would be... positive varying rate of change. `
yes that is correct. We have positive rate of change because the amount is growing. The rate of change varies (ie not constant) because the amount it grows by changes each time

Answer 16

so that leaves scenario 3 to be negative varying rate of change

the car is losing value, so it has negative rate of change
the amount it loses changes (varies) each time
