output(y)= 14, 15, 15, 16compare the data in the table with the relation f(x)=7x-15. which relation has a greater value when x=6?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
