Which of the following is the graph of the function f (x ) = x + 3 - 1?
Is there a radical in this function?
no I 4 graphs to choose from and I plotted points but it came out nothing like any of my choices
oh wait there is an absolute value
|x+3|-1
\[f(x) = |x+3| - 1\]
yes
So, we know that an absolute value graphs... look like a V right?
right

1. I am not artist so do not judge me... 2. That is the graph at its origin...
I have a V with the lines going up and a V with the lines going down
When it has +3 inside of the absolute it means go to the left 3 on the x-axis
-1 on the outside of the absolute value signs means go down 1 on the y-axis... you are moving the origin point to get a new special point

Yes!
ohhhh ok if I had a negative in the absolute value it would go the other way?
If you had a minus sign, yes.
If you have a minus sign on the outside on the left hand side... that means you flip it
flip it so the two lines go down?
Right
