The student's council is setting up a concession stand for a 24 hour relay. they plan on selling hot dogs and hamburgers. a maximum of 600 hamburgers and hot dogs are needed. from the previous year's relay the demand should be at least four times as many hot dogs as hamburgers. define the variables.

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.

-14 is the answer

hope this : ))
