If \(f(x) = x^2 - 4x + 3\), then find the values of \(f(1)\), \(f(-1)\), \(f(2)\), \(f(3)\). Also, find the zeros of the polynomial \(f(x)\).

Answer:

\(f(1) =\)

\(f(-1) =\)

\(f(2) =\)

\(f(3) =\)

The zeros of the polynomial \(f(x)\) are and .

(Note: For zeros of polynomial, enter the values in ascending order.)
