Look at interval [0,8] of graph from the following link:

1. For what values of x does the function have a local maximum on (0,8)
2. Local minimum
3. absolute maximum. I think it's none.
4. absolute minimum. I think it's 5

Best ResponseYou've already chosen the best response.1for 3 and 4 you are correct

Best ResponseYou've already chosen the best response.3I tried, but it says at least one of the answers is not correct.

Best ResponseYou've already chosen the best response.1perhaps the local maximum is only at x=3 because (0,8) implies 8 is not included in the interval (it would be if it were written [0,8]) do you have a limited number of chances to try?

Best ResponseYou've already chosen the best response.3It's unlimited tries. It's still incorrect.

Best ResponseYou've already chosen the best response.1I'm sure 3 and 4 are correct, and that x=3 is a local maximum, so what tricks are we missing?

Best ResponseYou've already chosen the best response.1This is giving me a headache. They are pulling some trick with the discontinuities and endpoints. I guess I'll have to get back to you. In the meantime just try whatever you can think of since you have unlimited chances, and let me know if you get it.

Best ResponseYou've already chosen the best response.1Local Max at (3,4). Local min (2,2). Absolute min (5,0) No Absolute Max

Best ResponseYou've already chosen the best response.1oh so our only mistake was calling x=5 a local min. I guess I forgot it can't be both absolute and global. thanks for the refresher:)

Best ResponseYou've already chosen the best response.1oh, I confused you with mertsj because you have the same picture, so I thought you had figured it out. nevermind...

Best ResponseYou've already chosen the best response.01. For what values of x does the function have a local maximum on (0,8) This is obviously (3,4). If 8 were in the intervali.e., the interval were (0,8], I'd say there is one at x = 8 as well, but it's not. 2. Local minimum (2,2) and (5,0) 3. absolute maximum. I think it's none. Yes I agree, because the function on the interval never attains a value greater than or equal to 4. absolute minimum. I think it's 5 Yes, because the value y = 0 which is less than or equal to every other value of f(x) on the interval (0,8) is attained at x = 5.

Best ResponseYou've already chosen the best response.11. x=3 2. x=2, x=5 3. none 4. x=5 Those are the answers I gave as well once I noticed that x=8 was not in the interval (you can read above to see that I eventually realized that) and still you can see the the questioner said this was wrong. I guess either he typed it incorrectly, or the internet site he is working on is faulty. I have found that happening all too frequently.

Best ResponseYou've already chosen the best response.0yes, I didn't try to figure out exactly who had said what to whom, but I feel very confident with my answer. So either his class is using a nonstandard definition, or there's something wrong with the software.

Best ResponseYou've already chosen the best response.3I figured out 1. 3 2. 2, 5 3. none 4. 0 I just realized that for number 4, it is asking for the yvalue
