Question

1. rick works as a mathematics tutor. he made the graph below to show the number of algebra students and the number of geometry students he helped in each of the last five weeks. ricks students what is the range of the relation represented by ricks graph? a. {2,3,4} b. {1,2,3,4} c. {1,3,4,5,6} d. {1,2,3,4,5,6}

Explanation:

Step1: Recall range definition

The range of a relation is the set of all the second - coordinate values (y - values).

Step2: Identify y - values from the graph

The y - values of the points on the graph are 2, 2, 3, 3, 4.

Step3: Write the range as a set

The set of unique y - values is $\{2,3,4\}$.

Answer:

A. $\{2,3,4\}$
