Answer:
Set A
Step-by-step explanation:
By definition "a function may NOT have two y-values assigned to the same x-value, [but] it may have two x-values assigned to the same y-value."(https://mathbitsnotebook.com/Algebra1/Functions/FNFuncBasics.html)
Set A has follows this set of rules while Set B does not. Also if we graph it, Set B does not pass the vertical line test. (Learn about the vertical line test in the link below).

If this is an exponent, it would be 4 x 4 x 4 x 4 x 4 in expanded form.
Answer:

Step-by-step explanation:
A polynomial is the sum of terms with variables having positive integer exponents. Coefficient numbers need not be integers.
The term 3/x^4 = 3x^-4 is not such a term, so the expression containing it is not a polynomial.
Answer:
88 adult tickets and 77 student tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be 8x and the number of student tickets sold be 7x.
adult tickets + student tickets = 165 tickets
8x + 7x = 165
15x = 165
x = 165 ÷ 15
= 11
No. of adult tickets sold (8x) = 11 × 8
= 88
No. of student tickets sold (7x) = 11 × 7
= 77
