Choose the function that represents the data in the table. x 0 1 2 3 4 5 y 6 6 point 5 7 7 point 5 8 8 point 5

As x increases by 1, y increases by 0.5 each time: 6, 6.5, 7, 7.5, 8, 8.5. A linear function with this rate of change and starting value y = 6 when x = 0 is y = 0.5x + 6. Therefore, the correct choice is D.
