Final answer:
No points given might be on the graph of the function.
Step-by-step explanation:
The given function has a domain of 0 to 15 and a range of multiples of 5 from 0 to 75. To determine which points might be on the graph of the function, we can consider the x and y values of each point. In this case:
- (10, 15): This point is not on the graph because the y-value does not correspond to a multiple of 5.
- (10, 80): This point is also not on the graph because the y-value is outside the range of the function.
- (20, 10): This point is not on the graph because the x-value is outside the domain of the function.
Based on these considerations, none of the given points might be on the graph of the function.
