Question

determine whether the following relation represents a function. give the domain and range for the \\{\\(7,9\\), \\(2,5\\), \\(-3, -3\\), \\(5,5\\)\\} does the given relation represent a function? yes no what is the domain? \\{\\} (use a comma to separate answers as needed.)

Explanation:

Step1: Recall the definition of domain

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

Step2: Identify the first elements

From the ordered pairs \((7,9)\), \((2,5)\), \((-3,-3)\), \((5,5)\), the first elements are \(7\), \(2\), \(-3\), and \(5\).

Answer:

\(\{-3, 2, 5, 7\}\)
