The collection of ordered pairs below represents a function: {(4,19), (-2, 77), (0, 10), (1/2,9/5 ), (1,10), (-3,0), (100, 100)} a. State the domain of the function.

b. State the range of the function.

Answers:

Explanation:

The domain is the set of possible x inputs of a function. The range is the set of possible y outputs of a function. Use curly braces to denote a set. The order doesn't matter. Note that the duplicate item "10" isn't listed twice, i.e. we only list each unique value once.

If your teacher requires you to sort the domain and range, then,

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
