1. A particle is moving on the x-axis (or any number line) Its position x(t), or distance from the origin, at the time t is given by x(t)=4t^3-16t^2+15t. t is greater than or equal to 0

a.) Where is the particle when it is at rest?

b.) During what time interval is the particle moving to the LEFT?

c.) When is the acceleration lest?

d.) What is the TOTAL distance traveled by the particle from t=0 to t=3 ?
