2. The graph of y = f (x) is shown below. ly = A(x) a. On the grid above, sketch the graph of y = f (x) +4 (1 mark) b. Describe the transformation(s) that occurred. Use the appropriate terms (translation, reflection and/or stretch) and identify any relevant axis or line of reflection with its equation. (1 mark) c. State the domain and range for y = f"(x) using interval notation. (1 mark) d. Restrict the domain of y = f (x ) so that the graph of y = f (x) is a function. State the restriction using interval notation. (1 mark)
