# Thread: Definite Integral problem

1. ## Definite Integral problem

So here's my problem:

Let $\displaystyle \int_0^9f(x)dx=7, \int_0^3f(x)dx=2 , \int_6^9f(x)dx=10$

Find $\displaystyle \int_3^6f(x)dx=$

and

$\displaystyle \int_6^3(7f(x)-2)dx=$

Any suggestions on how I could get started?

2. A near identical question was asked and answered yesterday.
