Using this model, the predicted number of owls in year 9 is about -
23. Does this prediction make sense? Why or why not?
O A. Yes, because the owl population is endangered.
O B. No, because the owls went to live somewhere else.
C. No, because you can't have a negative number of owls.
O D. Yes, because that is the result of substituting x = 9.
