x^(1/2) + 3x -10
x^-2 - 1
as long as the exponents are not positive whole numbers, the espressions are not polynonmial

A polynomial is a function of the form:
y = a + bx +cx^2 + dx^3 + ....
where the powers of x go to some n, called the degree of the polynomial, and the constants a,b,c,d,... are the coefficients of the polynomial. Any function you write that contains more than integer powers of x multiplied by constants would not be a polynomial:
y = sin(x)
y = Sqrt(x) = x^1/2
y = a +bx +cx^2 + dx^1/2
The last function can be written as the sum of a polynomial and a non-polynomial, which together is not a polynomial.

all mathematical functions are polynomials, and have a polynomial expansion.
this can be achieved in general by Taylor expansion,
there are also many other methods depending on the complexity of the original function.
