Find {eq}\int_0^8 (2f(x)-3g(x))dx{/eq} if {eq}\int _0^3 f(x)dx=17, \int_3^8 f(x)dx=-15{/eq}, and {eq}\int_0^8 g(x)dx=12{/eq}

The Fundamental Theorem of Calculus

If a function has a defined antiderivative, we can use the Fundamental Theorem of Calculus to find a numerical result for a definite integral by using the below statement.

{eq}\int_a^b f(x) dx = F(b) - F(a) {/eq}
