To solve quadratic functional equations, start by assuming the function ( f(x) ) is quadratic, i.e., ( f(x) = ax^2 + bx + c ). Substitute this into the given functional equation and expand. Then, equate the coefficients of corresponding powers of ( x ) on both sides to form a system of equations. Solving this system will yield the values of ( a ), ( b ), and ( c ) that satisfy the equation. For example, consider the equation ( f(x) + f(-x) = 2f(x) ). Substituting ( f(x) = ax^2 + bx + c ) gives ( f(x) + f(-x) = 2ax^2 + 2c ). Setting this equal to ( 2f(x) = 2ax^2 + 2bx + 2c ) leads to ( 2ax^2 + 2c = 2ax^2 + 2bx + 2c ). Simplifying, we find ( b = 0 ), so ( f(x) = ax^2 + c ). This method ensures that the function meets the specified conditions.
4.4 Solving Rational Functional Equations
Rational functional equations involve functions expressed as ratios of polynomials. To solve them, start by cross-multiplying to eliminate denominators, resulting in a polynomial equation.
