The value of the output r(-3) in the given function is 2.
<h3>How to Interpret Graphs?</h3>
When we talk about graphs like this, it is pertinent to note that the x-values are the input values which would give us corresponding y-values which are the output values.
Now, we want to find r(-3) from the graph. This means we want to find the value on the y-axis when x = -3.
From the given graph, we see that when x = - 3, it is traced that the value of the output is y = 2.
Thus, the value of the output r(-3) in the given function is 2.
