Question

Which graph represents the absolute value of -3?

Answer 1

The third graph

Explanation:

|a| = a for a ≥ 0

|a| = -a for a < 0

therefore

|3| = 3 and |-3| = -(-3) = 3

Answer 2

Graph 1 is the correct representation of absolute value of -3.

Explanation:

Absolute value of a number is the measure of positive distance on a number line from zero to that number.

It is denoted by:

`\mid c \mid = c, \text{if c} > 0\\ ~~~~~ = -c, \text{if c} < 0`

So, the absolute value of -3 =

`\mid -3 \mid = 3`

The correct representation of the absolute value option 1.

As the graph in option 1 represents the positive distance between zero and -3.
