Function Composition Calculator

Compute the composite function (f∘g)(x) for two linear functions and evaluate it at any point x. Perfect for precalculus students learning how function composition works.

f(x): Coefficient a

f(x): Coefficient b

g(x): Coefficient a

g(x): Coefficient b

Algebra

2x2 System of Equations Solver

Solve a 2×2 system of linear equations in the form a₁x + b₁y = c₁ and a₂x + b₂y = c₂ using Cramer's rule. Returns the x-coordinate of the intersection of the two lines; foundational for any problem with two unknowns and two constraints.
