Y left t right 3 t 2 2t 1 solution. Remember that domain refers to the x values that are represented in a problem and range refers to the y values that are represented in a problem. The questions cover a wide range of concepts related to functions such as definition domain range evaluation composition and transformations of the graphs of functions. The range of a function f consists of all values f x it assumes when x ranges over its domain.

To see that we observe that the natural domain of this function is 1 since we request that the expression from which we extract the square root is non. The solutions are at the bottom of the page.
