Question: The period T (in seconds) of a simple pendulum is a function of its length l (in feet) defined by the equation where g
The period T (in seconds) of a simple pendulum is a function of its length l (in feet) defined by the equation

where g ≈ 32.2 feet per second per second is the acceleration of gravity.

(a) Use a graphing utility to graph the function T = T(I).
(b) Now graph the functions T = T(I + 1),T = T(I + 2), and T = T(I + 3).
(c) Discuss how adding to the length I changes the period T.
(d) Now graph the functions T =T(2I),T =T(3I), and T = T(4I).
(e) Discuss how multiplying the length 1 by factors of 2,3, and 4 changes the period T.
T = 2 g
