# Find the length of curve by integration, quadratic equation

Consider that two particles are traveling the paths of the following functions:

f(x)=3/4x^2-x+1

g(x)=-x^2+2x+3

If each particle is to begin at one point of intersection at the same time and travel to the other point of intersection (at the same velocities), then which particle would arrive first? WHY?
