Answer:
C) (f+g)(x)= <em>3</em><em>x</em><em>^</em><em>3</em><em>-</em><em>2</em><em>x</em><em>^</em><em>2</em><em>+</em><em>1</em><em>0</em><em>x</em><em>-</em><em>1</em><em>2</em>
Step-by-step explanation:
The particle is at rest when the derivative of x(t), which is its velocity, is zero, i.e.,
![\dfrac{d}{dt}[x(t)] = \dot{x}(t) = 0](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdt%7D%5Bx%28t%29%5D%20%3D%20%5Cdot%7Bx%7D%28t%29%20%3D%200)
Since
its derivative is

Equating this to zero, we get

This is a familiar quadratic equation whose roots are




This means that the particle will be at rest at t = 3 and t= 4.
