Question #9cf14
1 Answer
Graph the function using a table of values, making sure to include the vertex.
Explanation:
The general form of an absolute value equation is
Where:
If
To graph using transformations, we look at the parent function (in this case
In the example provided above,
The table of values for the parent function looks like this:
X | Y
-2 | 2
-1 | 1
0 | 0
1 | 1
2 | 2
The transformed table of values would look like this:
X + h | aY + k
-2-2=-4 | -1(2)+0=-2
-1-2=-3 | -1(1)+0=-1
0-2=-2 | -1(0)+0=0
1-2=-1 | -1(1)+0=-1
2-2=0 | -1(2)+0=-2
(Sorry about the table format...)
