Not completely sure.
The zeros of the function occur when the graph meet the x-axis so in this case the zeros occur at B ( 0 and 5)
Well 33 is rounded down to 30
And 89 is rounded up to 90
So it would be 120
Anything from 1-4 is rounded down and anything 5-9 is rounded up
Mean is the average
So the first mean is 11
The second one is 14.7 so round to 15
15-11 is 4. Hope that is correct
