    application of integration

    i have 2 functions f(x) = x +1 and f(x) = (x-1)^2 I am supposed to figure out the area between the 2 functions without making any calculations....this is where im having trouble, i sketched the 2 graphs the x-1 function is a parabola facing up and the other function is a line that sits on top of it, but how am i supposed to know the area from that? unless i used graph paper and counted the boxes in between the functions? well if you come with an answer please let me know thanks.

    integrate the two functions then take the difference. with the limits of integration being to two intersecting points.

    thank you but i cannot make any calculations, i have to draw the two graphs and then rationalize what the area will be.

    I don't think there is a way to get the exact area between the two curves without integration because of the parabola
