Checkpoint: Non-Polynomial Parent Functions Solution
Explain why the domain values for a cube root parent function are all real numbers, but for the square root parent function the domain is numbers greater than or equal to zero.
The cube root of a negative number can be determined so any real number can be the radicand. The radicand of a square root (principal root) must be a value greater than or equal to zero because only real numbers are graphed on the coordinate plane.
Note
You will also compare polynomial parent graphs to non-polynomial parent graphs.
Go back and read the end behavior statements out loud for the parent functions so you connect the notation with the correct words.
