Substituting values from the domain will give the corresponding values from the range.
Practice makes perfect
We can graph the linear function using a table. First, let's 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)=-4+7x
Simplify
0
g( 0)=-4+7( 0)
g(0)= -4
1
g( 1)=-4+7( 1)
g(1)= 3
2
g( 2)=-4+7( 2)
g(2)= 10
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.
