Question

find the domain of the function defined by the set of points below. express your answer as a set of n
(0, -8), (7, 7), (-5, -2), (-3, -9)

Explanation:

Step1: Recall domain definition

The domain of a function (defined by ordered pairs \((x,y)\)) is the set of all \(x\)-values (first elements) of the ordered pairs.

Step2: Extract \(x\)-values

From the ordered pairs \((0, -8)\), \((7, 7)\), \((-5, -2)\), \((-3, -9)\), the \(x\)-values are \(0\), \(7\), \(-5\), and \(-3\).

Step3: Form the domain set

Collect these \(x\)-values into a set.

Answer:

The domain is \(\{-5, -3, 0, 7\}\)
