Allison is saving to buy a $500 dollar bicycle by working during summer vacation.

-the job pays her $8 for every 1 hour worked
-allison works exactly 20 hours each week

if she works for 4 weeks and buys the bicycle, how much money will she have left over?

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.
