B. Warm air rises,and cool air sinks.
Given:
The piecewise function is

To find:
The range of given piecewise function.
Solution:
Range is the set of output values.
Both functions
and
as linear functions.
Starting value of
is at x=-4 and end value is at x=3.
Starting value: 
End value: 
Starting value of
is at x=3 and end value is at x=6.
Starting value: 
End value: 
Least range value is 0 at x=-4 and 0 is included in the range because -4 is included in the domain.
Largest range value is 11 at x=6 and 11 is not included in the range because 6 is not included in the domain.
So, the range of the given piecewise function is [0,11).
Therefore, the correct option is A.
