I need help with these math problems.

assign all written homework pages Sparky D Dragon is taking the water tari between Navy Pier and the Museum Campus. Suppose the distance between the tari and Navy Pier is given by the function f(t) = 3t + 1 measured in feet, where t is time measured in seconds. Find the average velocity of the water tari in ft/s between the following values for t. Show all your work! (a) (1 point) t = 2 and t = 4 seconds. (b) (1 point) t = 2 and t = 3 seconds. (c) (3 points) t = 2 and t = 2 + h seconds. Simplify your answer as much as you can! (d) (1 point) What is the instantaneous velocity at t = 2 seconds? Do this by finding the limit as h - 0 of the average velocity that you found in part (c). Page 1
