10-138.
  1. If f(x) = x2 − 2 then:

  2. f(x) − 3 = (x2 − 2) − 3

    also

    f(2x) = (2x)2 − 2

    = x2 − 5

    = 4x2 − 2

  3. Use these same ideas with f(x) = (x + 1)2 − 3 find these expressions: 10-138 HW eTool (Desmos). Homework Help ✎

    1. f(x) + 3

    2. f(3x)

    3. 3 · f(x)

    4. f(x + 3)
