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 p(x) will give us the corresponding values from the range.
x
p(x)=4x
Simplify
0
p( 0)=4( 0)
p(0)= 0
1
p( 1)=4( 1)
p(1)= 4
2
p( 2)=4( 2)
p(2)= 8
Using these x and p(x) values as ( x, p(x)) coordinate pairs, we can plot the points. Connecting these points will give us the graph of the function.
