1-126.

Identify the domain and range of the functions below. Then write a possible piecewise function for each. Homework Help ✎

a.

b.

Domain is the set of values that x can be, while range is the set of values that y can be.

Regarding the piecewise function:
Each piece has its own domain; be careful about open or closed intervals. Notice that both pieces are linear.

Notice that this graph has both a vertical and a horizontal asymptote, which may affect the domainand range respectively.

Regarding the piecewise function:

Note that there is a gap between the two functions. So the boundary point on the left will be different from the boundary point on the right.
