Answer:

I don't know what kind of form your assignment wants it in, but the domain (span over the x axis) is -4<=x<=5, and the range is -3<=x<=5. Perhaps write it is as "-4 to 5" for domain and "-3 to 5" for range.

Evaluate

lakkis [162]

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

See attachment for the graph of the piece-wise functions
