Hi Tutors!

Please help me with this question Part B, including explanation and all steps. I am submitting Part A separately in case it is too long to submit as one question. So Part B is what I'm interested in. Thanks!

n Define the functions In (2) = n +1 on O else the closed interval [0,1] 00 Then consider the function f(x) = > In (x) defined on [0,1]. 71=1 (a) Using the partition P = 10, , 1} find the upper and lower Darboux sums for f. (b) Prove or disprove that f is integrable on the interval [0,1]
