Dear Tutors,

Please take on this question and include steps. 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]
