differentiate the function, then put the differentiated equation = 0 you will have either one answer or 2, if you get two answers, the one which has negative value will be the maximum value of the function ;)

does the max. value asked here is the x or the y value?

@dan18 , the correct way is to differentiate and equate to zero , but just by looking at this question once can tell it's maximum value is infinity for x=infinity....pretty weird question i guess...are u sure u hv typed the question correctly

wouldn't it be y'= 2/((2x)^(1/2))

dan18Best ResponseYou've already chosen the best response.1
I get x=2 @ y', then subts. it to the eq. does the max. value = 0?

@dan18 is the question correct ?

hartnnBest ResponseYou've already chosen the best response.1
but actual answer is infact Max. value = 0 when x=2 http://www.wolframalpha.com/input/?i=y%3D4+sqrt%282x%29

akash_809Best ResponseYou've already chosen the best response.0
now u hv got the correct question, yes the max would be zero
