What step are you on?
1. I don't know where to begin.
2. I have begun but got stuck midway.
3. I got an answer but I was told that it's wrong.
4. I got an answer and would like my work checked.
5. I have a question about someone else's work/solution.
6. I have completed the problem and don't need help anymore. Thank you.
7. None of the above

Also is it m+b or m+M ? Not that it matters that much but just checking

you dont need to use maxima minima for this just analyse this in the interval given

because 3 is positive an exponential function will also be sort of the same parabolic shape as the quadratic
