Graphing Absolute Values

We didn't do much today...
In the morning, we just worked on our exercises then a REALLY short lesson in the afternoon.

The lesson was about graphing absolute values.

As you can see, the x-intercepts (zeroes or roots) for the absolute graph (green graph) are -3 and 3.

This is because if you set the y to zero

y = x - 3
0 = x- 3
x = -3

y = x + 3
0 = x + 3
x = 3



It is important to remember that: ABSOLUTE VALUE ALWAYS HAS TO BE POSITIVE. (in the graph)

Since you can't have a negative value... the graph will just bounce and go the opposite direction.








the absolute value of -1 is 1 therefore the graph will just keep on bouncing and it will never have a negative value.


That is it for now... if i missed anything please inform me.

The next scribe is JAMILYN G.
