(x-1)x^(2/3)
i found the derivative: which was: (5x/3)^(2/3)-2/(3x^(1/3))
and the only critical number i could find was: 5x-2=2/5
and the interval given was [0,1]
so wuld i jsut use 2/5,0,and 1? are there any more critical numbers?
would 3/5 be one? (1-(2/5)) and yes that is my solution...and i have graphed the function...my minimum value was correct, but the graph went to positive infinity...so can i still have a maximum?
