Q. Find the domain of the function defined by the set of points below. Express your answer as a set of numbers.(−5,9),(3,−2),(8,−6),(−8,−7)Answer:
Define Function Domain: The domain of a function is the set of all possible input values (usually x-values) for which the function is defined. To find the domain of the function given by the set of points, we need to list all the unique x-values from the given points.
Identify Unique X-Values: The given set of points is (−5,9), (3,−2), (8,−6), (−8,−7). The x-values from these points are −5, 3, 8, and −8.
Express Domain as Set: Since the domain is simply the set of these x-values, we can express it as a set of numbers. The domain of the function is {−8,−5,3,8}.
