10-118.
  1. If f(x) = 5x + 2 then: 10-118 HW eTool (Desmos). Homework Help ✎

  2. f(x)3 = (5x + 2) 3

    also

    f(2x) = 5(2x) + 2

    = 5x 1

    = 10x + 2

  3. Use these same ideas with f(x) = 3x −2 find these expressions:

    1. f(x) + 3

    2. f(3x)

    3. 3 · f(x)

    4. f(x + 3)

f(x) + 3 =
3x − 2 + 3=

3x + 1

f(3x) = 3(3x) − 2

3(3x − 2)

Use the same method as part (b).
