x * +11. 16 2 16. Let f(x) (a) Using the method of completing the square, find the coordinates of the vertex of the graph of y= f(x). (2 marks) (b) The graph of y = g(x) is obtained by reflecting the graph of y = f(x) about the x-axis. The graph of y = h(x) is obtained by translating the graph of y = g(x) vertically. If the graph of y=h(x) touches the straight line y = 6, find the y-intercept (3 marks) of the graph of y=h(x). x * +11. 16 2 16.
