The period T of a pendulum in seconds, which is the time for the pendulum to return to the point of release, is given by the equation T=1.1 where, L is the length of the
pendulum in feet. Find the length of the pendulum if the period is 17.6 seconds

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
