Match the graph with its function using the x-intercepts.
A. f(x) = x1/2 + 2x1/4 + 1 B. f(x) = x1/2 - 15x1/4 - 16 C. f(x) = x1/2 + 2x1/4 - 1 D. f(x) = x1/2 + 15x1/4 - 16
Provide an appropriate response.Suppose a car dealer has showrooms in Atherton and Berkeley and warehouses in Concord and Dublin. The cost of delivering a car is $60 from Concord to Atherton, $45 from Concord to Berkeley, $50 from Dublin to Atheron, and $35 from Dublin to Berkely. Suppose that the showroom in Atherton orders 7 cars and the showroom in Berkeley orders 4 cars. Also suppose that the warehouse in Concord has 8 cars and the warehouse in Dublin has 6 cars available. Find the best way to minimize cost and find the minimum cost. (Hint: Let x1 be the number of cars delivered from Concord to Atherton and x2 be the number of cars delivered from Concord to Berkeley. Thus 7 - x1 is the number of cars delivered from Dublin to Atherton and 4 - x2 the number of cars shipped from
Dublin to Berkeley.) What will be an ideal response?
