Question

= 2x ln x + 9,

Answer 1

Hi what's the full equation?

Answer 2

you are asked to write 2x ln(x + 9) as a single log, right ?

Answer 3

f(x) = 2x ln x + 9,

[1, 2]
Find all points c satisfying the conclusion of the MVT for the following function and interval

Answer 4

You can use a ln(x) = ln(x^a) here I think

Answer 5

Mean value theorem?

Answer 6

ya

Answer 7

you just plug in 2 and 1, find the slope between them (i.e. the difference between f(1) and f(2)). Then derive the function and solve for the aformentioned slope.

Answer 8

just to clarify, you'd want f(2)-f(1)/2-1
or vice versa, please don't mix them up.

Answer 9

i did it, thanks guys
