Someone can help me solve a doubt, in this exercise supposing that the function that limits more area is the line y=6, and the minimum area limits is y=3, the results coincide, however I do not understand why these two functions are valid, since they do not fulfill the condition of max=6 and min=3 simultaneously.
(I have done it integrating y=6 between x=2 and x=4 for the maximum area y
integrating y=3 between x=2 and x=4 for the minimum area.)
Thank you.
