I need help with this problem please, and please make it legible.

The position of a particle in the xy-plane at time t is r(t) = (t- 1) i+ (t2 + 3) j. Find an equation in x and y whose graph is the path of the particle. Then nd the particle's velocity and acceleration vectors at t =4. The equation for the path of the particle is y= :l. The velocity vector at t= 4 is v = (I ) i +( )j. (Simplify your answers.) The acceleration vector att= 4 is a =( ) i +( )j. (Simplify your answers.)
