Answer:
ten and a half
Step-by-step explanation:
2×3.5= 7
3×3.5= 10.5
The answer is choice C) All real numbers from 0 through 35.
The domain is the set of allowed inputs (x). The points on this graph have x coordinates that span from x = 0 to x = 35. Because x is time in minutes, we can have fractions of a minute (eg: x = 7.5 ---> 7 and a half minutes). So we won't just have integers.
