Please Help! Knowing the negative sign (–) also means "opposite", how do you we read this expression, -8 • 2?

Negative eight times two? not quite sure what you are asking

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.

31 is prime. and it’s prime factorization is just 31.
