Sketch the graph of the function. Describe how the graph can be obtained from the graph of a basic exponential function.f(x) = 2 ? 4(x - 1) + 4
A. Shift y = 4x right 1 unit(s), stretch it
vertically, and shift it up 4 unit(s)
B. Shift y = 4x right 1 unit(s), stretch it
vertically, reflect across the x-axis, and
shift it up 4 unit(s)
C. Shift y = 4x left 1 unit(s), stretch it
vertically, reflect across the x-axis and
shift it up 4 unit(s)
D. Shift y = 4x left 1 unit(s), stretch it
vertically, and shift it up 4 unit(s)

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?
