WebMethod 2: Multiplying through by the common denominator: The lowest common denominator is 15. Rather than converting the fractions to this denominator (something that would be required if I were adding or subtracting these rational fractions), I can instead multiply through (that is, multiply both sides of the equation) by 15. WebIf we have f(x) in the equation, replace it with y. Solve the equation for x. Set the denominator of the resultant equation ≠ 0 and solve it for y. Set of all real numbers other than the values of y mentioned in the last step is the range. Example: Find the range of f(x) = (2x + 1) / (3x - 2). Solution: Let us replace f(x) with y.
