Exercise 6 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+5|-3 Simplified Absolute Value g(x)
-8 g( -8)=| -8+5|-3 g( -8)=(3)-3 0
-5 g( -5)=| -5+5|-3 g( -5)=(0)-3 -3
-2 g( -2)=| -2+5|-3 g( -2)=(3)-3 0
0 g( 0)=| 0+5|-3 g( 0)=(5)-3 2
2 g( 2)=| 2+5|-3 g( 2)=(7)-3 4
5 g( 5)=| 5+5|-3 g( 5)=(10)-3 7
8 g( 8)=| 8+5|-3 g( 8)=(13)-3 10

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