Alex is correct the book would cost $18.52 before taxes adding 10% tax the book would cost an additional $1.85 for a total of $20.37. This would be just under the $21.00 that both Alex and Laura had to spend. Laura tried to combined the 35% discount which you cannot do. So yes they both would be able to purchase the book.

Answer:
y = csc(x) -1
Step-by-step explanation:
The vertical offset of -1 is your first clue. Your second clue is that the range does not include (-2, 0), typical of cosecant and secant functions (offset by -1).
_____
<em>Comment on answer choices</em>
Apparently the cosine choices are intended to be confused with the cosecant choice. The cosine function has a range of [-1, 1], so will not show any vertical asymptotes anywhere, regardless of scaling or translation.
First you need to make table value
Second y=5x+3
Y is your output and x is your input
