Exercise 4 Page 475

Start with making a table of values for x and g(x).

Practice makes perfect

In order to graph the given absolute value function, we can make a table of values.

x	g(x)=\|x+7\|-1	Simplified Absolute Value	g(x)
-8	g( -8)=\| -8+7\|-1	g( -8)=(1)-1	0
-4	g( -4)=\| -4+7\|-1	g( -4)=(3)-1	2
0	g( 0)=\| 0+7\|-1	g( 0)=(7)-1	6
4	g( 4)=\| 4+7\|-1	g( 4)=(11)-1	10

Now we can graph g(x) by plotting the points and connecting them with straight lines on either side of the vertex.
