Explanation of Solution
Given information: Graph the function ,
Calculation:
The graph of the function is given below.
Calculation:
The domain of f is
Basically all x except when tan(2x) is discontinuous.
The range of tan 2x is all real numbers so the range of
f is not differentiable where it is discontinuous ,this is at
The graph consists of line segment ,all with slope of 2.
