Question

what is the range of these points? check all that apply. (8, 2), (12, 9), (16, 16), (20, 23) 20 23 2 12 9 16 8

Explanation:

Step1: Recall the definition of range

The range of a set of data (in this case, the \(y -\)values of the points \((x,y)\)) is the difference between the maximum and minimum values. But if we consider the range as the set of \(y -\)values (which is also a common interpretation in the context of functions, where for a set of ordered pairs \((x,y)\), the range is the set of all \(y\) values).
The \(y -\)values of the points \((8,2)\), \((12,9)\), \((16,16)\), \((20,23)\) are \(y_1 = 2\), \(y_2=9\), \(y_3 = 16\), \(y_4=23\).

Step2: List the range values

The range (set of \(y -\)values) is \(\{2,9,16,23\}\).

Answer:

2, 9, 16, 23
