6. You are given a graph of y = 1/f(x). It shows two curved lines, one opens up and left, the other opens down and right. On the left and up you can see that it intercepts (1,1). On the right and down you can see it intercepts (3, -1). You can see the asymptotes are y = 0 and x = 2. Which of the following points are valid on y = f(x). Hint: draw it. ' A. (3, 0) B. (-1, 3) C. (2, 2) D. (-4, -1)
