$$f(x)=x^3-11x^2+41x-51$$ .

A polynomial function is a function that can be expressed in the form $$f(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0$$ where $$a_n, a_{n-1}, ..., a_0$$ are constants and $$n$$ is a non-negative integer.

The degree of a polynomial is the highest power of the variable in the polynomial.

The formula for compound interest is $$A = P(1 + \frac{r}{n})^{nt}$$ where A is the amount, P is the principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

To find the zeros of a polynomial function, set the function equal to zero and solve for the variable.

The zeros of a polynomial are the values of x that make the polynomial equal to zero, and each zero corresponds to a factor of the polynomial.
