After typing 1/4 of a term paper on Friday, Richard completed 2/3 of the remainder on Saturday. If he wanted to finish the paper that weekend, what part was left to be typed on Sunday? a=1/4 b=2/3 c=1/3 d=1/2

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.

None of the options you showed are it.
