Parametrizatian of a path Find a vectorvalued function r(t) = [m(t),y(t),z(t}] which parametrizes the line beginning at t = U at the point [1, 4,2] and passing through the paint [3, 4, 1] at t = 1. Give your answer as a vector using square brackets, ie. [ expression in x, expression in y, expression in 2 J PM = |_
