The volume (in cubic meters), v, of a rectangular room is given by the expression:
v = 7b^4-28
where b is a positive integer and each dimension is a positive integer too. what are three unique expressions that could represent the dimensions of the room?
write these three expressions as a product that equals the volume (e. g. "(expression 1)(expression 2)(expression 3)").

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.
