Answer 1

@hartnn can you give me a hand?

Answer 2

did u differentiate f(x) ? what u got ?

Answer 3

ya 3-11/x sorry god disconnected from the internet

Answer 4

yes, now equate that to 0 and solve for x

Answer 5

so x=11/3

Answer 6

yes, put that back in f(x) to get the critical value.

Answer 8

x=0 is incorrect.

Answer 9

11-11 log(11)

Answer 10
