In a volatile housing market, the overall value of a home can be modeled by V(x) = 415x² - 4600x + 200000, where V represents the value of the home and x represents each year after 2020.
Part A: Find the vertex of V(x). Show all work.
Part B: Interpret what the vertex means in terms of the value of the home.
