A tire can hold c cubic feet of air . It loses a percentage of its air during each period of time t . This rate of loss , written as a decimal , is r . This situation can be described using the following formula : C(1-r)t. What effect if any does increasing the value of r in the value of c ?

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.
