Answer:
only (2) and (4) are polynomial out of given options.
Step-by-step explanation:
Polynomial is an expression having variables having positive integer exponents with real constant coefficients. example 
We are given some polynomials and we have to choose whether are polynomial or not.
Consider ,
1) 
Since, Polynomial does not have a fractional exponent.
So, 1) Not a polynomial.
2) 
Since all of the variables have integer exponents that are positive this is a polynomial.
3) 
Not a polynomial because a term has a negative exponent
.
4) 
Since all of the variables have integer exponents that are positive this is a polynomial.
Thus, only (2) and (4) are polynomial out of given options.
"on sale for 12% off" means that whatever the price is (y) we multiply it by 0.88 since 1-0.12 = 0.88
Price before discount = original price = y
Price after discount = 0.88y
Put another way, we took 88% of the original price to get the discount price.
------------------------------------
Now tack on the sales tax. We do this by multiplying the discount price by 1.03 (1 + 0.03 = 1.03)
So we have:
final cost = 1.03*(discount price)
final cost = 1.03*(0.88y)
final cost = 0.9064y
telling us that the final cost is 90.64% of the original price (y). With the tax added, the discount is not 12% but actually 100% - 90.64% = 9.36%
