# How do you graph #y =1/x^2#?

##### 1 Answer

The graph of this function looks like a bell centred around the y axis.

#### Explanation:

First you must ensure that the denominator is different from zero so you set:

The y axis becomes a vertical asymptote of your function; basically the graph of your function will be a curve that gets as near as possible to the y axis without ever crossing it.

When

So your graph will look like:

graph{1/x^2 [-10, 10, -5, 5]}

This function is particularly interesting when describing the phenomenon of Resonance in physics!
