Substituting values from the domain will give the corresponding values from the range.
Practice makes perfect
Let's graph using a table. First select some arbitrary values from the domain, then substitute them for x in the given equation. Solving for p(x) will give us the corresponding values from the range.
x
p(x)=-3x-1
Simplify
0
p( 0)=-3( 0)-1
p( 0)= -1
2
p( 2)=-3( 2)-1
p( 2)= -7
4
p( 4)=-3( 4)-1
p( 4)= -13
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 equation.
