# How do you find the domain and range of y = 1/x^2?

Sep 2, 2015

The domain is color(red)(x≠0); the range is $\textcolor{red}{y > 0}$.

#### Explanation:

$y = \frac{1}{x} ^ 2$

$\frac{1}{0}$ is undefined, so $x$ cannot equal $0$.

The domain is x≠0.

${x}^{2}$ is always positive, so the range is $y > 0$.
