This table show the population of owls in a park in different years. The quadratic regression equation that models these data's

is y=-1.34^2+10.75x-11.3 .
x values represent year : 1,2,3,4,5,6
y values represent number of owls : 0,2,7,14,9,4

Using this model the predicted number of owls in year 9 is about -23. Does this prediction make sense ? Why or Why not?

A: Yes,because the owl population is endangered .
B: No, because the owls went to live somewhere else.
C: Yes, because that is the result of substituting x=9
D: NO, because you can't have a negative number of owls.

Answer: D) No, you cannot have a negative number of owls

This applies to any creature, person or thing in general. A negative number of something doesn't make any sense. So there are limits to how useful the regression is.
