Match the graph with its function using the x-intercepts.
A. f(x) = (x - 3)2 - 3(x - 3) - 4 B. f(x) = (x - 3)2 + 3(x - 3) - 4 C. f(x) = (x - 3)2 + 9(x - 3) + 14 D. f(x) = (x - 3)2 - 9(x - 3) + 14
Solve the problem.Under a certain apportionment method State X receives 41 seats and State Y receives 29 seats. Ten years later, the population of State X has increased by 5%, while the population of State Y remains unchanged. Under the same apportionment method, State X now receives 40 seats and State Y receives 30 seats. This is called
