Consider the domain and range of each piece separately . Then combine.

Domain: Both 2* ^{x}* and 3

*x*− 2 have a domain of all real numbers.

Range: 2

*on*

^{x}*x*≤ 2 has a range of 0 <

*y*≤ 4 and 3

*x*− 2 on

*x*> 2 has a range of 4 <

*y*.

Later in this course we will learn a formal definition of continuity. For now, think about what continuous means to you. Now look at the graph at *x* = 2. Make a conclusion and justify.

Consider other values of *x*, other than *x* = 2. Is the function continuous at these point? Is there anywhere where the function will not be continuous?
