Q. Find the range of the function defined by the set of points below. Express your answer as a set of numbers.(−2,−3),(3,9),(−10,0),(−5,7)Answer:
Identify Given Points: To find the range of the function, we need to look at the y-values of the given points, as the range consists of all possible y-values that the function can take.The given points are (−2,−3), (3,9), (−10,0), and (−5,7).
List Y-Values: List the y-values of the points: −3, 9, 0, 7.
Find Smallest and Largest: To find the range, we need to identify the smallest and largest y-values from the list.The smallest y-value is −3 and the largest y-value is 9.
Determine Range: The range of the function is the set of all y-values from the smallest to the largest, inclusive.Therefore, the range is the set of numbers from −3 to 9, which can be expressed as [−3,9].
