- 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.arrow_forwardShow all work to solve 3x² + 5x - 2 = 0.arrow_forwardTwo functions are given below: f(x) and h(x).
