Question

Help Please... i got stuck on the values that i found and which would be my abs max/ min
this is what i got

Answer 1

@raffle_snaffle or anyone

Answer 2

Your derivative is wrong, it's \[-2x^{-3}\ln x+\frac{x^{-2}}{x}\]
Do you need more help to study the function given that?

Answer 3

yes i found the derivative

Answer 4

but idk if i did it correctly

Answer 5

@NiceMathyGuy marcelie's derivative is correct.

Answer 6

Ah sorry I misunderstood your answer. your answer is correct, and the function reaches its maximum in \[e^{\frac{1}{2}}\]

(it's increasing on \[[\frac{1}{2},e^{\frac{1}{2}}]\] and decreasins on \[[e^{\frac{1}{2}},4]\].

So the min is reached either in \[\frac{1}{2}\] or \[4\].

Answer 7

okay so how would i find the abs values ?
