Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x - 9)?

a.) the graph of y = f(x) will shift up 9 units.
b.) the graph of y = f(x) will shift down 9 units.
c.) the graph of y = f(x) will shift left 9 units.
d.) the graph of y = f(x) will shift right 9 units

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.
