the graph of the relation t is shown below. give the domain and range of t. write your answers using set…

Explanation:

Step1: Identify the domain

The domain is the set of all (x -)values of the relation. Looking at the graph, the (x -)values of the points are (-2) and (2). So, the domain (={-2,2}).

Step2: Identify the range

The range is the set of all (y -)values of the relation. Looking at the graph, the (y -)values of the points are (-2), (2.5), (3). So, the range (={-2,2.5,3}).

Answer:

domain (={-2,2}), range (={-2,2.5,3})
