Q. Find the domain of the function defined by the set of points below. Express your answer as a set of numbers.(1,4),(−1,−1),(−4,−6)Answer:
Identify input values: The domain of a function is the set of all possible input values (x-values) for which the function is defined. To find the domain of the function given by the set of points (1,4), (−1,−1), (−4,−6), we need to list the x-values of these points.
List x-values: The x-values of the given points are 1, −1, and −4. These are the only input values for which the function is defined, as each corresponds to a point in the set.
Define domain: Since the function is defined only at these specific points, the domain is simply the set of these x-values. Therefore, the domain of the function is {1,−1,−4}.
