Question 508519
False, it is vertical. In fact, all "functions" where you have x = ?  are vertical lines because their slopes are undefined.  If you think about the definition of slope, it is  (change in y / change in x).  Since our x value is fixed, then the change in x is 0, right?  Then we have division by 0, and so we result in a vertical line, which isn't a function since it obviously does not pass the vertical line test.
