2. An exponential function has undergone the following transformations. - It was stretched by a factor of 2 vertically o It was compressed horizontally by a factor of 2 and translated 3 units left a The key points of the parent function are: (1.3), (0.1} and (1%) o It was vertically translated 3 units down a. What is the formula representing the mapping notation? [2 marks] b. What are the three transformed points? [1 mark] c. What is the new horizontal asymptote? [1 mark] d. Write the equation representing the above transformation [2 marks] e. Provide a sketch on the following page. Your sketch must be clear, indicating the horizontal asymptote and the three transformed points clearly labelled. [2 marks] 2 -6.5 6 -5.5 -5 5 -4 -3.5 -3 -2.5 -2 -1.5 -1 -0.5 0 0.5 1.5 2 2.5 -1 -2 -3
