Answer:
1.np
2.p
3.p
4.p
5.np
Step-by-step explanation:
Polynomials don't have negative degree like in no. 1. All polynomials have nonnegative degree.
For no. 5, it must be √5 x not √5x to become a polynomial because functions containing other operation such as square roots are not polynomial.
2-4 are obviously polynomials
All and all, polynomials are the sum of terms of the form k•x^n. where k is any number and n is nonnegative integer, also, x is any variable.
