SUMMARY
The discussion centers on the analysis of the function s(t) = t^3 - 3t to determine the intervals where the object is speeding up. The first derivative, s'(t) = 3t^2 - 6, reveals critical points at t = ±√2. The second derivative, s''(t) = 6t, indicates that the object is speeding up when t > 0, as this is when acceleration is positive. A correction was noted regarding the derivative of 3t, which is 3, not 6, but this does not affect the intervals where the object is speeding up.
