Aveterinary clinic plans to build four identical dog kennels along the side of its building using 210 feet of fencing. (see the picture.) what should be the dimensions of each kennel to maximize the enclosed area? (note: no fencing is needed along the side of the building.)

the square root of what number? if you add that, then someone will probably answer the question.

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.
