Answer:
domain is (0, 30)
Range is (1900, 2500)
Step-by-step explanation:
We are told that Jessica plans to decrease her calorie intake by 40 calories every 2 days for the next 30 days.
This means that the domain of this period is between 0 days to 30 days.
Thus, the domain is (0, 30)
Now,she plans decrease of 40 calories every 2 days. This amounts to an average of 20 calories a day.
Which means that in a month of 30 days, she would have decreased her daily calorie intake by; 20 × 30 = 600 calories.
Since she is currently on 2500 calories per day, it means that the new targeted daily intake is; 2500 - 600 = 1900 calories.
Thus, the range for this situation would be between 1900 calories and 2500 calories.
Range = (1900, 2500)
