Question

write whether the following functions of polynomials or not ?
give reasons for your answer

a) x^3 + 1/x^2+ 1/x + 1
b) x^2+x+3
c) y^-1/2-3y+2
d) √2y^3+√3y​

Answer 1

here the first option is not a polynomial as the power of the second term is not a whole number. the rest have whole numbered powers for the variables so they are polynomials
