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

Explanation:

Step1: Recall domain definition

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

Step2: Identify x - values

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

Step3: Form the domain set

We collect these x - values into a set. The set of these x - values is \(\{-5, - 3,0,7\}\).

Answer:

\(\{-5, - 3,0,7\}\)
