By making use of the change of variable y = x + 3 write the integral below in a form where the range of integration is
All I know to do is to substitute x + 3 into the integral where y is. I'd guess minusing 3 from the x + 3 could be what's required to have the integral in the form where the range is .
(By the way "minusing" is not a word in the English language. Use "subtracting" instead.)
