how do you find displacement and average velocity for an interval given?

Question

the interval is 0 is less than of equal to x and x is less than or equal to 2. the equation is s=t^2-3t+2.

Answer 1

The displacement is the change in position. So it would be

s(2)-s(0).

The average velocity is the change in position divided by the change in time. So it would be

(s(2)-s(0)) / (2-0)

Note that the numerator is the displacement that you calculated previously
