Let s(t), v(t) and a(t) be functions giving the position, the velocity, and the acceleration of the object at time t. whic...

Section 1.2 What is point-slope form? - ANSWER-y-y1=m(x-x1) Section 1.3 What is the average rate of change? How do you find it? - ANSWER-The average rate of change is the slop of the function between any two times. You find it by solving for the slope. Section 1.3 What is relative rate of change? How do you find it? - ANSWER-Relative change is usually expressed as a percentage with no unit. You can find it by using the equation (p1-p0)/(p0). Section 1.3 How do you know if something is c...
