(02.06 HC)Let y = 2(x – 4)2 – 8. Pаrt A: Is the given relаtiоn а functiоn? Is it оne-to-one? Explain completely. If it is not one-to-one, determine a possible restriction on the domain such that the relation is one-to-one. (5 points) Part B: Determine y–1. Show all necessary calculations. (5 points) Part C: Prove algebraically that y and y–1 are inverse functions. (5 points)
