A piece-wise function combines more than one functions of different input values.
The value of f(-1) is -3
From the graph, we have the following observations
- When x = -1, y = -3
- When x = -1, y = -4
Notice that there is a closed circle at the point where x = -1 and y = -3.
This means that y = -3 is inclusive of the values of y on that particular function
However, there is an open circle at the point where x = -1 and y = -3.
This means that y = -4 is exclusive of the values of y on that particular function
The correct corresponding value of y is when y is inclusive.
Hence, the value of f(-1) is -3
