What is the mean for Doctor A’s data set on glasses? What is the mean for Doctor B’s data set on glasses? Write a sentence comparing the number of people who wear glasses in the two data sets.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

0 is its x and y coordinate

where are the choices?
