A scale measure weight to the nearest 0.1 pounds which is the most appropriate way to report weight using this scale

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.

A= the square root of 3“if letters are anything like people, they’re all equal and deserve to be treated equally.”
