Which of the following is not an example of polynomial function ?
A function f: R → R is said to be a polynomial function if for each x in R,
Y = f(x) = a0 + a1 x + a2x2 + … + an xn, where n is a non – negative integer and a0, a1, a2, …, an ϵ R.
Give an example for a function which is not a sequence.
