-Suppose that $\int _ { 6 } ^ { 8 } \mathrm { f } ( \mathrm { x } ) \mathrm { dx } = 5$. Find $\int _ { 5 } ^ { 5 } \mathrm { f } ( \mathrm { x } ) \mathrm { dx }$ and $\int _ { 8 } ^ { 6 } \mathrm { f } ( \mathrm { x } ) \mathrm { dx }$.
A) $0 ; 5$
B) $0 ; - 5$
C) $5 ; 5$
D) $5 ; - 5$

Question

Quizplus · Accepted Answer

The integral of a function from a to a is always 0, and reversing the limits of integration changes the sign of the integral.
