question 6

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.
- $$f ( x ) = \frac { x + 1 } { x - 4 } ; [ - 10,10 ] \text { by } [ - 10,10 ]$$

• A) one-to-one; \(f ^ { - 1 } ( x ) = \frac { 4 x - 1 } { x + 1 }\)
• B) one-to-one; \(f ^ { - 1 } ( x ) = \frac { x - 4 } { x + 1 }\)
• C) one-to-one; \(f ^ { - 1 } ( x ) = \frac { 4 x + 1 } { x - 1 }\)
• D) not one-to-one
