Both calculators run independently — change the inputs on either side to compare results.

Rational Function Analyzer

Analyze a rational function of the form (num_a·x + num_b) / (den_a·x + den_b) to find its vertical asymptote, horizontal asymptote, domain, and intercepts. Useful for precalculus and calculus students.

Numerator: Coefficient of x

Numerator: Constant

Denominator: Coefficient of x

Denominator: Constant

Analysis Focus

Fill in the required fields to see your result.

Algebra

Polynomial Roots Calculator

Find the primary real root of a polynomial of degree 2, 3, or 4 from its leading coefficient, second coefficient, and constant term. Returns one root for an approximate guide; full root-finding for arbitrary polynomials needs symbolic algebra or numerical methods.
