Example 1 Express each relation as a table, a graph, and a mapping. Then determine the
domain and range.
1. {l-1, -1), (1, 1), (2, 1), (3, 2)}
2. {(0,4), (-4, - 4), (-2,3), (4,0)}
3. {(3,-2), (1, 0), (-2, 4), (3, 1)}
pls help

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

f(x)=2/3x-8, which give g(x) the greatest value.
