Suppose the area of the region between the graph of a positive continuous function f and the x-axis from x = a to x = b is 4 square units. Find the area between the area between the curves y = f(x) and y = 2f(x) from x = a to x = b.(adsbygoogle = window.adsbygoogle || []).push({});

Attempt:

Since 2 f(x) is greater than f(x) we can call it g(x) and that will be the dominant function.

[tex]\int (g(x) - f(x)) dx[/tex]

It becomes...

[tex]G(x) - F(x)[/tex]

What do I do next?

Thanks
