The graph of the equation 2
= 4 is the tilted ellipse pictured below; i.e. the points (x,y) in
the plane that satisfy the equation yield the pictured ellipse.
This is NOT the graph of a function
. However, if you solve the original equation for
in terms of
you can break the graph into two pieces, each of which is the graph of a function as pictured below.
(a) The upper piece of the ellipse (solid) is the graph of the function
