How would one might parametrize y = x^2(adsbygoogle = window.adsbygoogle || []).push({});

Here is the problem

"an object moves along the parabola y = x^2 from (0,0) to (2,4). One of the forces acting on the object is F(x,y) = (x+2y)i + (2x+y)j. Calculate the work done by F."

the soluction manual has r(t) = ui + u2j -- [0,2]

I forgot how to parametrize this type of function(y = x^2), and how to get the limits of integration of [0,2]?

Thanks

Philip
