question 36

Multiple Choice

Use a graphing calculator to graph the function using the given viewing window. Use the graph to decide if the function
is one-to-one. If the function is one-to-one, give the equation of the inverse function.
- $$f ( x ) = \frac { - x } { x + 2 } ; [ - 8,8 ] \text { by } [ - 8,8 ]$$

• A) one-to-one; \(f ^ { - 1 } ( x ) = \frac { - 2 x } { x + 1 }\)
• B) not one-to-one
• C) one-to-one; \(f ^ { - 1 } ( x ) = \frac { 2 x } { x + 1 }\)
• D) one-to-one; \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { - \mathrm { x } } { \mathrm { x } + 2 }\)
