Question

F(x)=7-2x polynomial function

Answer 1

Explanation:

Yes, F(x)=7-2x is a polynomial function for which the sole x term has the exponent 1 and the constant term has the exponent 0:

F(x) = -2x^1 + 7x^0

As is true of all polynomial functions, the exponents are all positive integers (plus that of the constant term is zero).
