3. In the figure, the graph of y=4" cuts the y-axis at A, and passes through B(1,4) . C and D are the images of A and B after reflecting about the line y=x respectively. (a) Write down the coordinates of A. ( b ) Mark the points C and D with their coordinates on the figure. y = 4* y= x (C ) Sketch the graph of y=log, x on the figure. [4 marks] B (1, 4) 4. It is given that f (x)= x2_ and g(x)=-1 x+1 Below are the graphs for y=f(x) and y=g(x) y=f (x) y=g (x) Are the graphs for f(x) and g(x) identical? Briefly why. [2 marks] P. 9 of 12
