Lesson 24 Practice

  1. Asymptotes. a) x=-1 , y=6 b) x=4 , y=-1 c) x=2 , y=0 d) x=-3 , y=0
  2. Match The Graphs.

    f(x)= \frac {x+2}{x+1} C

    g(x)= \frac {3x}{x+1} D

    j(x)= \frac {3}{x-5} A

    k(x)= \frac {x+1}{x} B

  3. Interval Behavior I.

    Interval to the left of the vertical asymptote: (-\infty,4) , decreasing

    Interval to the right of the vertical asymptote: (4,\infty) , decreasing

  4. Interval Behavior II.

    Interval to the left of the vertical asymptote: (-\infty,-1) , increasing

    Interval to the right of the vertical asymptote: (-1,\infty) , increasing

  5. Interval Behavior III.

    (-\infty,-2) , increasing

    (-2,2) , includes maximum

    (2, \infty) , decreasing

  6. Interval Behavior IV.

    (-\infty,-2) , decreasing

    (-2,-5) , decreasing

    (5,\infty) , decreasing
