Extracted text: 2. Note: m=4 7 4-x a. Let f-1(x) = .Find f (x). т+4x b. If g(x) = 3 + v2x – m and f(x) – 1 = x2 , then find (fog)(x) in the simplest form? c. Use the horizontal line test to test a linear, a quadratic and cubic function whether one-one function or not. Provide your solution by giving a correct example for the three functions and justify your answers.
