This is my Real Life Functions with my teammate Lan. Our Independent Variable was the different types of sodas we had. Our Dependent Variable is the number of calories in each of our sodas. So our Domain is the sodas and Range is the number of calories. The function will fail because each soda has different a chance of being in a different container, can, or bottle. This will mean that the calories would not be the same for each same brand of soda so that would make this a relation.
