Exercise 6 Page 403

A function in the form of y= 1x-h+k has a vertical asymptote at x=h and a horizontal asymptote at y=k. To determine whether the value of each constant h and k is positive, negative, or zero, let's determine the intersection of the asymptotes for the given graph.

As we can see, the horizontal asymptote lies along the x-axis and the vertical asymptote lies in Quadrant II and III. Therefore, h is negative and k is zero.
