im given a problem that gives me y=7-8x+x^(2) and it says calculate the exact area between the x-axis and the graph of y. What i have done is tried using the fundamental theorom, by saying that F(b)=2600, and F(a)=2600. I got these values by graphing and looking at where the y graph starts and stops. but when i use the fundamental theorom i get a bogus answer. The answer given in the book is 36, can any1 point me in the correct direction please?
