4. a. Determine the mapping notation of the form (x, y) -> (_, _) from y = f(X) for each of the following. (4 marks) i. y = 3f(2X) +1 1 ii. y= - Iflx- 2)) iii. y=2f%x+4) -3 b. A point (- 6, 3) lies on f(X) from part a. Determine the new location of the point for the functions in parts a, b, and c of question 4. (3 marks) I. ii. iii. c. The point (4, -3) lies on the graph of the function y = 90:). State the ordered pair after each indicated reflection. (3 marks) i. Reflected about the line y = x ii. Reflected about the line x = 0 iii. Reflected about the line y = O
