Exercise 7 Page 123

Substituting values from the domain will give the corresponding values from the range.

Practice makes perfect

Let's graph the linear function using a table. First, select some arbitrary values from the domain. Then, substitute them for x in the given function. Solving for g(x) will give us the corresponding values from the range.

x g(x)=- x+4 Simplify
0 g( 0)=-( 0)+4 g(0)= 4
2 g( 2)=-( 2)+4 g(2)= 2
4 g( 4)=-( 4)+4 g(4)= 0

Using these x and g(x) values as ( x, g(x)) coordinate pairs, we can plot the points. Connecting these points will give us the graph of the function.
