  1. Parent Functions P.7

  2. Parent Functions Y = x2 Dom [-∞, ∞] or All Real Numbers Range [0, ∞ ] Called the quadratic function

  3. Parent Functions Y = √x Dom [0, ∞ ] Range [0, ∞ ] Called the root function.

  4. Parent Functions Y = 1/x Dom All reals except x = 0 Range All reals except y = 0 Called the rational function.

  5. Parent Functions Y = |x | Dom [-∞, ∞] or All Real Numbers Range [0, ∞ ] Called the abs value function.

  6. Parent Functions Y = x Dom [-∞, ∞] or All Real Numbers Range [-∞, ∞] Called the Identity function.

  7. Parent Functions Y = x3 Dom [-∞, ∞] or All Real Numbers Range [-∞, ∞] Called the cubic function.

  8. Called the cube root function. Dom : All Reals Range: All Reals

  9. The Step functions. Also know as y = [x], int (x) Dom : All Reals Range: Intergers

  10. The goal is to know these parent functions so we can then quickly graph any translation of them. HW Make index cards of the functions.
