I can't say I understood your question, but refering to the title of the thread, the area between two 'well-behaved' functions f and g on the interval [a, b] is given with [tex]\int_{a}^b(f(x)-g(x))dx[/tex], if f(x) >= g(x), for every x from [a, b].NIZBIT said:

A little hint- if you area comes out negative, then you have the two curves in the wrong order!

Find the area between these two curves-

y=x^2-4x+3

y=3+4x-x^2

Now how do you know which is f(x) or g(x)?

What? Neither is "f(x)" or "g(x)" untilNIZBIT said:
