I presume you are talking about -intercepts when you say vertical and -intercepts when you say horizontal. -intercepts is(are) the point(s) where a graph intersect(s) the -axis. -intercepts of the graphs of functions are ordered pairs that always have the form . -intercepts is(are) the point(s) where a graph intersect(s) the -axis and are ordered pairs that always have the form where all are contained in the set of zeros of the function.

The x-intercept occurs where +y+=+0+
The y-intercept occurs where +x+=+0+
--------------------------------
There can be more than one x-intercept,
but there can be only one y-intercept
-------------------------------
Suppose you have the equation +y+=+x%5E2+-+4+
To find the x-intercept(s),
+0+=+x%5E2+-+4+
+x%5E2+=+4+
+x+=+2+
+x+=+-2+
----------
And, to find the y-intercept,
+y+=+0%5E2+-+4+
+y+=+-4+
----------
Here's the plot:
