is the velocity Intervals [0,3]

Acceleration at 2?

When is it farthest to the left? Why?

When does it change direction? Why?

What is the total distance traveled from 0 to 3?

This is on my math test today, nad I was wondering if I got it right..

I got..

-1.586

Mr F says: +1.586.
-2.5066283 because velocity>0

Mr F says: t = +2.5066 (because v = 0).
-2.5066283 because it goes from - to +

Mr F says: t = +2.5066.
-I got 2.197

Mr F says: d = distance travelled left + distance travelled right = 3.2655 + 1.0683 = ....
Was I right? Wrong?
