Can someone help me solve this question?? Show me the method would be really nice of you. Thanks in advance!!

(3} Find the value of c that satises the conclusion of the Mean Value Theorem for the function f(x) = lnx on the interval [2, 12]. {h} [f f{l} = T" and f'{x) E 3 for l i: x :1 5 then: according to the Mean Value Theorem, what is the smallest possible value for f{5) '? {e} Let f be the function whose graph is shown below. 3- 4 5 6 '1" 3 9 10 ll Estimate the two values of c that satisfy the conclusion of the Mean Value Theorem on the interval [4, 10]
