On a trip to his friend's house, Raphael's average speed was 45 miles per hour. The distance that Raphael is from his friend's house at a certain moment in the trip can be represented by d = 150 - 45t, where d represents the distance in miles and tis the time in hours. Find the zero of this function. Describe what this value means in this context.

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.
