1

f(x)= |x+4|

2

f(x)= |x-4|

3

f(x)= |x| + 4

12

Multiple Choice

Choose the correct equation for the graph.

1

$y=\left|x+2\right|$

2

$y=\left|x-2\right|$

3

HINT: For the vertex, you will always use the opposite of what you see for the h and exactly what you see for the k.

If a is positive your graphs opens up, if a is negative your graph opens down
