I need the 1 and number two to be answered In the interval

The function s(t) = 613 _ 35 to + 5t represents the position function for a particle moving along a line (1 dimensional motion) for t in [0, 5]. a.) Find the intervals where the particle is moving to the right. If there is more than one interval, separate your answers by a comma. b.) Find the itnervals where the particle is moving to the left. If there is more than one interval, separate your answers by a comma. Question Help: Video Written Evamale ..
