Use the graph of \( f(x) \) to determine whether the function is one-to-one. If it is, find a formula for its invers \[ f(x)=\frac{x+2}{x-9} \] Is the function one-to-one? Yes No

Step 1
- A function is one-to-one if each output value corresponds to exactly one input value. This can be checked using the horizontal line test on the graph of the function. If any horizontal line intersects the graph more than once, the function is not one-to-one. Show more…
