A 0.165-kg ball, moving in the positive direction at 10 m/s, is acted on by the impulse shown in the graph below. What is the ball's speed at 4.0 s?

You do not provide a graph. You need to compute the impulse applied during the 4 seconds. Add that to the momentum at t = 0. That will be the final momentum. Divide final momentum by 0.165 m for the speed.
