Problem 15 of 7
Calculate average rate of change for rational function f(x)=(x+1)/(x-2) on interval [3,5].
Using a hint is okay. It just tells the trainer to give you a little more review.

Hidden until you reveal it.
Evaluate valid endpoints and avoid intervals crossing restrictions when continuity over interval is required.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Check endpoints and interval for denominator restrictions.
2. Evaluate function at valid endpoints.
3. Compute the change quotient or state why it is not meaningful.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Computing across a vertical asymptote as if the function were continuous.
