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, select some arbitrary values from the domain, then substitute them for x in the given function. Solving for h(x) will give us the corresponding values from the range.
x
h(x)=-3/4x-1
Simplify
0
h( 0)=-3/4( 0)-1
h(0)= -1
4
h( 4)=-3/4( 4)-1
h(4)= -4
8
h( 8)=-3/4( 8)-1
h(8)= -7
Using these x and h(x) values as ( x, h(x)) coordinate pairs, we can plot the points. Connecting these points will give us the graph of the function.
