# How do you solve and write the following in interval notation: x > -2?

Jul 28, 2016

$\left(- 2 , \infty\right)$
First, begin by noticing that $x > - 2$ means that you want all the points greater than $- 2$. Thus, you don't want the actual point $- 2$. So that's why we use the ( bracket rather than the [ bracket.
Now, since every number greater than $- 2$ is on our interval, we put $\infty$ to the right.
The reason we also use the ) bracket, is because technically infinity is not a real number.
