Work with function notation. Read each answer as an input-output pair.

  1. 1.For f(x) = 5x − 3, find f(4).
  2. 2.For f(x) = 5x − 3, find f(0).
  3. 3.For f(x) = 5x − 3, find x when f(x) = 22.
  4. 4.For g(x) = 2x + 1, find g(6) and g(−2).
  5. 5.One input gives two different outputs. Is it a function? Why?
  6. 6.What point on the graph does f(3) = 12 describe?
