Question
Graphs of the position functions of two particles are shown, where t is measured in seconds.
When is the particle in figure (a) speeding up? (Enter your answer using interval notation.)
____________________
When is the particle in figure (a) slowing down? (Enter your answer using interval notation.)
____________________
When is the particle in figure (b) speeding up? (Enter your answer using interval notation.)
________________________
When is the particle in figure (b) slowing down? (Enter your answer using interval notation.)
_______________________ (a.) It says that (0,1) and (3,4) speeding up are wrong, as well as (1,3) slowing down.
(b.) i entered (3,4) for speeding up and (0,3) for slowing down. It says these are wrong too. Please help

a)[0,1]constant velocity,
reversed its velocity direction,
[1,3]constant velocity,again reversed direction of velocity
,[3,4]constant velocity but greater velocity then previous one
b)[0,1]speeding,(notice change of convexity of curve at point (1,0)
[1,2]slowing,
[2,3]constant velocity,
reversed direction of velocity and then [3.4]constant velocity
