Draw the graph of `y=(1)/(x^(2))`.

Explanation

We have `y= f(x)= (1)/(x^(2))`.
Clearly, the domain of the function is `R-{0}`.
Now `" "underset(x to 0^(+))lim (1)/(x^(2))=oo and underset(x to 0^(-))lim (1)/(x^2)=oo`
`" "underset(x to oo)lim (1)/(x^(2))=0 and underset(x to -oo)lim (1)/(x^2)=0`
When `x` increases from 0 to `oo, (1)/(x^2)` decreases from `oo` to 0.
Also the function is even. So the graph of the function is as shown in the following figure.
