Transportation An appliance company has a warehouse and two terminals. To minimize shipping costs, the manager
must decide how many appliances should be shipped to each
terminal. There is a total supply of 1200 units in the ware-
house and a demand for 400 units in terminal A and 500
units in terminal B. It costs $12 to ship each unit to terminal
A and $16 to ship to terminal B. How many units should be
shipped to each terminal in order to minimize cost?

-2 is the right

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
