The function s gives the displacement (in feet) of an object as a function of time (in seconds). Calculate values of the average velocity for the given values of t and find the instantaneous velocity at the indicated value of t by noting the limit of the average velocities.s = 7t - 7; when t = 4; use values of t of 3.5, 3.9, 3.99, 3.999
A. Average velocities: 7, 7, 7, 7
v = 7 ft/s
B. Average velocities: 27.5, 27.9, 27.99, 27.999
v = 28 ft/s
C. Average velocities: 28, 28, 28, 28
v = 28 ft/s
D. Average velocities: 6.5, 6.9, 6.99, 6.999
v = 7 ft/s
