### Complexity=1, Mode=graph

Find the absolute value of the number which is represented by x.

 1.   | x | = 2.   | x | =

### Complexity=1

Evaluate.

 1.   | 4 | = 2.   | -22 | =

### Complexity=1, Mode=graph

Find the absolute value of the number which is represented by x.

1
| x | =
Solution

Begin by figuring out the value of x.
x = -1
x is 1 away from 0.
The absolute value of x is 1.

Alternate Explanation:
x = -1
Since -1 is negative, we know that | x | = -x.
This means | x | = | -1 | = 1.
2
| x | =
Solution

Begin by figuring out the value of x.
x = -2
x is 2 away from 0.
The absolute value of x is 2.

Alternate Explanation:
x = -2
Since -2 is negative, we know that | x | = -x.
This means | x | = | -2 | = 2.

Evaluate.
