Answer:
[tex]B(-1) = 1\\\\B(3) = 0\\\\B(1) =2[/tex]
Step-by-step explanation:
By definition, a relation is a function if each input value has one and only one output value.
The input values are the x-values and the output values are the y-values.
Given:
[tex]B(-1),B(3)[/tex] and [tex]B(1)[/tex]
We can identify that we need to find the output values of these input values:
[tex]x=-1\\x=3\\x=1[/tex]
Observe in the graph attached that:
Therefore:
[tex]B(-1) = 1\\\\B(3) = 0\\\\B(1) =2[/tex]
