- The rule for differentiating constant functions is called the constant rule. It states that the derivative of a constant function is zero; that is, since a constant function is a horizontal line, the slope, or the rate of change, of a constant function is (0).

May 28, 2023 · Given a polynomial function f(x),f(x), use the Rational Zero Theorem to find rational zeros. Determine all factors of the constant term and all factors of the leading coefficient. Determine all possible values of pq,pq, where pp is a factor of the constant term and qq is a factor of the leading coefficient.
Each rational zero of a polynomial function with integer coefficients will be equal to a factor of the constant term divided by a factor of the leading coefficient. When the leading coefficient is 1, the possible rational zeros are the factors of the constant term.
Aug 15, 2024 · The Rational Zero Theorem states that, if the polynomial \(f(x)=a_nx^n+a_{n−1}x^{n−1}+...+a_1x+a_0\) has integer coefficients, then every rational zero of \(f(x)\) has the form \(\frac{p}{q}\) where \(p\) is a factor of the constant term \(a_0\) and \(q\) is a factor of the leading coefficient \(a_n\).
Each rational zero of a polynomial function with integer coefficients will be equal to a factor of the constant term divided by a factor of the leading coefficient. When the leading coefficient is 1, the possible rational zeros are the factors of the constant term.
