The cost for roberta's college next year is $11,000. she has a grant for $1,500 and a scholarship of $5000. she plans to earn 40% of the remaining amount. how much will still be left to pay?

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.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
