Rectangle E G H J is shown. Point F is the midpoint of side E G and point I is the midpoint of side J H. The length of E F is 3, the length of F G is 3, and the lengths of G H and E J are 4. Through which points should a line of rotation be placed to create a cylinder with a radius of 3 units? E and J F and I J and G G and E

the answer is F and I

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.
