Difficult# Potential energy change in a finite distance for a given F(x)

APPHMC-PWZZY4

The conservative force exerted on a given particle as a function of position x is found to be $F(x) = \frac {-3} {x+1}$ for positive $x$ values, where x is given in meters.

From $x = 1 m$ to $x = 3 m$, by how much does the particle's potential energy change?
