Hector left his house at (−5,7) on a map of Coleville and walked to the zoo at (−5,6). From there he walked east to his friend's house. He walked a total distance of 23 blocks. If each unit on the map represents one block, what are the coordinates of Hector's friend's house?

The coordinates are

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.

If you make you answer for clear i can answer it : )
