CPM Homework Help : CALC Problem 1-53

Convert the following domain and range from interval to set notation. Then sketch a possible function.

$D = ( - \infty , 2 ) \cup ( 2 , \infty )$

$R = ( - \infty , - 1 ) \cup ( - 1 , \infty )$

Hint 1:

Hint 2:

The range indicates that this graph never reaches the height of $y = -1$ .

More Help:

The graph of this function could have a hole, jump or vertical asymptote at $y = 2$ .
