A particle is moving along a curve so that x(t)= t^2-4t+8 and y'(t)= te^(t-3)-1. Find the time t, 0 4, ≤ ≤t when the line tangent to the path of the particle is horizontal. Is the direction of
motion of the particle toward the left or toward the right at that time?
What is t= 2.2079 and the particle is moving right
