Particle Displacement from Acceleration

A particle moves along a straight line. For time $t \geq 0$, the acceleration of the particle is given by $a(t) = 4t + 2$. At time $t = 0$, the velocity of the particle is $-1$ and its position is $4$. What is the displacement of the particle over the time interval $0 \leq t \leq 3$?
