2 solutions....

(1) One with positive leading coefficient, the other with negative
Example: y=x^2-1 and y=-x^2+1
graph:

(2) Same thing, but with different axes of symmetry
Example: y=x^2-1 and y=-x^2+2x
graph:

(3) Two with different positive leading coefficients; vertices one above the other
Example: y=x^2 and y=(1/2)x^2+1
graph:

or 1 solution....

(1) same vertex but opening different directions (single intersection at the common vertex)
Example: y=x^2 and y=-x^2
graph:

(2) single intersection not at either vertex
Example: y=x^2+2x and y=-x^2+2x
graph:
