Lesson 31 Practice

  1. Spot the Asymptotes. a) y=0 b) x=0 c) y=0
  2. Shifting Functions.

    a) f(x) = log (2x) - 4: vertical, down, 4

    b) f(x) = log (2x - 4): horizontal, right, 2

    c) f(x) = log (2x) + 4: vertical, up, 4

    d) f(x) = log (2x+4): horizontal, left, 2

  3. Characterizing Inverses. All three boxes should be checked
  4. Evaluate the Log. a) 2 b) -1 c) 1/2
  5. Fill in the Blanks.

    positive real numbers __ real numbers

    vertical __ x=0 __ (1,0)

    10^x __ increasing
