I am having trouble with a maths problem, if anyone can at all help please try to do so:
A)For what value(s) of a does this function have a local minimum at x=2?
B)Show that this function can not have a local maximum for any value of a.
I have spent a lot of time looking at youtube lectures, google, my study guide etc.
I am still unsure of the process,
any help would be really appreciated.
Thank you very much for your responses, but it is more so the second part I am finding difficult. sorry for not specifying that. I get what I am supposed to do I just don't know what I can use to prove there is no maximum when there is a variable, but seriously thank you very much for responding, I really didn't expect to be answered so quickly. but if anyone could tell me what formula, theorem etc. to use to show there is no maximum, that would really help.
