The output value is 3 when the input is -1
Here, we want to get the output value for x = -1
To get the output value, we have to take a look at the graph
We need the value of y when x = -1
Looking at the graph, we have this as
y = 3
We only need to get the point at which x = -1, trace it to the function, then find the y-value corresponding
