Can I graph a polynomial of degree five or higher?

No, this calculator is designed for polynomials up to degree four. For higher-degree polynomials, other methods or tools would be needed to analyze the function.

What types of points does the calculator identify on the graph?

The tool identifies the roots (x-intercepts) and critical points, which include local extrema (maxima and minima) and inflection points where the curvature changes.

Do I need to enter all coefficients, including zeros?

Yes, you should enter values for all coefficients down to the constant term. Entering zero for any missing term ensures the polynomial degree and graph are calculated correctly.

Can the calculator show the step-by-step process for finding roots?

The calculator provides the computed roots and critical points directly, but it does not display the algebraic steps or factorization process used to arrive at those results.
