Functions: domain, range, and notation — Homework

Find each domain (and one range), then evaluate. Write domains in interval notation where you can.

  1. 1.Find the domain of f(x) = sqrt(x - 8).
  2. 2.Find the domain of g(x) = (x-3)/(x+4).
  3. 3.Evaluate f(x) = 3x^2 - 2x + 1 at x = -1.
  4. 4.What is the range of f(x) = sqrt(x-8)?
  5. 5.Explain why the domain of g(x) = (x-3)/(x+4) excludes x = -4.
