90 students went to the zoo three had a hot dog, soda and a popsicle ; 24 have a hot dog; five had a hot dog and soda; 33 had a soda ; 10 had a soda and popsicle; 38 had a popsicle ; eight had a popsicle and a hot dog. how many students did not have nothing? ?

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.

i think the answer is true
