Re: Quadratic Equation
Replace the x with a t .
V(t) = (t-3)(t-4) where t= time .
V(t) is the velocity function with respect to time . If you're interested in time t for when the velocity of some moving object is 0 then you find the roots . The displacement function is S(t) such that S'(t)=V(t) .
It's obvious that between t=3 and t=4 there is negative velocity and for t>4 , the velocity becomes positive .
