# How do you solve the inequality #x^2>=absx# and write your answer in interval notation?

##### 1 Answer

#### Explanation:

There are several ways to solve this:

**Algebraically**

If

then we can examine the two cases:

**Graphically**

Compare the graphs of

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Since the solution is a union of two ranges we use the

The range for

extends to

and

includes **is** part of the solution, so we use the "closed" parenthesis to show that it **is** included:

Similarly for the
