Function Composition Calculator

Evaluate the composite function (f∘g)(x) = f(g(x)) for linear, quadratic, exponential, or logarithmic f and linear g at any x value. Use it to check composition homework or explore how nested functions behave.

Function f(x) Type

f(x) Coefficient a

f(x) Coefficient b

g(x) Coefficient a

g(x) Coefficient b

Evaluation Point x

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.
