Bobby and Rick are in a 12-lap race on a one mile oval trac. Bobby, averaging 86mph, has completed two laps just as rick is getting his car onto the track. What speed does Rick have to average to be even with Bobby at the end of the twelve lap?

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.

The answer simplified would be. -6300x
