When you graph a tangent function, the asymptotes represent x values 90 and 270.
A cartesian graph is a graph in which y is some function of x. This is the 'normal' type in which you can give an x and y coordinate. Other types include polar in which modulus is a function of argument, but there are loads of varieties and forms.

The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
a) A circle is not the graph of a function. b) A circle is not linear.

A graph represents a function if and only if every input generates a single output.

The zeros of a polynomial represent the points at which the graph crosses (or touches) the x-axis.

Bar graphs do this. There are actually a few different kinds of bar graph, but they all have the same basic function.
Because each vertical lines meets its graph in a unique point.
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
