Let f: ℝ − {2} → ℝ − {3} be the bijective function defined by f(x) = (3x + 1)/(x − 2). What are the rule of its inverse function f⁻¹(x) and the value of f⁻¹(5), respectively?

f⁻¹(x) = (3x − 1)/(x + 2) and f⁻¹(5) = 2 f⁻¹(x) = (2x + 1)/(x − 3) and f⁻¹(5) = 11/2 f⁻¹(x) = (x − 1)/(x − 3) and f⁻¹(5) = 2 f⁻¹(x) = (x + 2)/(3x − 1) and f⁻¹(5) = 1/2

Correct Answer:

f⁻¹(x) = (2x + 1)/(x − 3) and f⁻¹(5) = 11/2
