METHOD 1: Store teh elements of the domain
as a list of values in L1.
Enter: { - 8 , - , - 6 , - 4 , - 2
, 0 , 2 , 4 , 6 , 8 }
To calculate the range values, compute
the right-hand side of the equation, substituting L1 for x
Enter: 2.5 + 4
The solution set is {(-8, -16), (-6,
-11), (-4, -6), (-2, -1), (0, 4), (2, 9), (4, 14), (6, 19), (8,
24)}
METHOD 2: Store the equation in the Y=
menu of the calculator and view the table of values it creates.
Enter: 2.5 X,T,q + 4 - 8 2
A table with columns X and Y1 appears
on the screen. The values in the Y1 column represent the corresponding
range values for each x value in the domain. This table helps
you find the ordered pairs that are solutions for the equation.
The solution set is {(-8, -16), (-6, -11), (-4, -6), (-2, -1),
(0, 4), (2, 9), (4, 14), (6, 19), (8, 24)}, which agrees wiht
the list in Method 1.
