To write a polynomial function in factored form based on the given zeros and their multiplicities, we use the following information:
- The zero at \(0\) has a multiplicity of \(2\): This contributes the factor \(x^2\).
- The zero at \(5\) has a multiplicity of \(3\): This contributes the factor \((x - 5)^3\).
- The zero at \(-1\) has a multiplicity of \(4\): This contributes the factor \((x + 1)^4\).
Now, we can combine these factors to write the polynomial function in factored form:
\[
f(x) = x^2 (x - 5)^3 (x + 1)^4
\]
This polynomial is expressed in factored form, taking into account the multiplicities and the order in which factors were included. Hence, the final form is:
\[
f(x) = x^2 (x - 5)^3 (x + 1)^4
\]
