Final answer:
The numbers in a range from greatest to least for the given function Y = 1/2X + 3 are 6, 5, 4, and 3.
Step-by-step explanation:
The function is given as Y = 1/2X + 3. To find the numbers in a range from greatest to least for the domain values of 0, 2, 4, and 6, we substitute each value into the function and calculate the corresponding Y values.
For X = 0, Y = 1/2(0) + 3 = 3.
For X = 2, Y = 1/2(2) + 3 = 4.
For X = 4, Y = 1/2(4) + 3 = 5.
For X = 6, Y = 1/2(6) + 3 = 6.
Therefore, the Y values in decreasing order from greatest to least are: 6, 5, 4, and 3.
