Best ResponseYou've already chosen the best response.1when you put x=1 the absolute value is positive when you put x=2 and three absolute value is negative (thats why i put  sign in front of second integral ) for x=4 and 5 absolute value is again positive .

Best ResponseYou've already chosen the best response.1yes it is because at x=0 still abs (x^5x+4) =(00+4)=4 positive .

Best ResponseYou've already chosen the best response.0Should the second integral be from 1 to 4 instead of 1 to 3, and the third integral be from 4 to 5?

Best ResponseYou've already chosen the best response.0so the second integral should be from 1 to 4, and the 3rd one 4 to 5?

Best ResponseYou've already chosen the best response.1\[\Large \int\limits_{0}^{1} (x^25x+4)dx\int\limits_{1}^{4} (x^25x+4)dx+\int\limits_{4}^{5}(x^25x+4)dx\]
