Question: 1. The velocity of a particle moving along the x-axis is given by f(t) = 6 - 2t cm/sec. Use a graph of f(t) to find the exact change in position of the particle from time t = 0 to t = 4 seconds.
2. Find the difference between the upper and lower estimates of the distance traveled at velocity f(t) on the interval a ≤ t ≤ b for n subdivisions.
f(t)=5t + 8, a = 1, b = 3, n = 100
