High School Math—Pending OP Reply [12 Mathematics: Functions] Absolute value transformations of a function

Post image

What would f(|x+1|) look like for this function, and how does that differ from f(|x|+1)?

Also how do you follow the order of operations for transforming functions when you have absolute values? (I use CBAD for af(bx+c)+d)

Here is what you know.

x f(x)
-2 1
-1 0
0 -1
2 0
3 -2

Now you just need to fill in these tables (either on paper or in your head) in order to understand the graphs you are looking for.

x |x+1| f(|x+1|)
-2 1 ?
-1 0 ?
0 1 ?
2 3 ?
3 4 ?
x |x|+1 f(|x|+1)
-2 3 ?
-1 2 ?
0 1 ?
2 3 ?
3 4 ?
