**Henry**, Thursday, March 24, 2011 at 6:54pmGraph the Eq and draw a vertical line

through it. The line will intersect the

graph at only one point. Therefore, the Eq is a function; because it passed the vertical line test.

If you graph an X-parabola and perform

the vertical line test, the line will

intersect the graph at 2 points. There-

fore, the X-parabola is not a function;

because it does not pass the vertical

line test.
