Ch 1 Real World Function

This is my real world function project about the different types of sodas under Pepsi Co and the amount of calories they each have. A function is the relation between x and y, where for every input value of x, there's only one output value of y. A relation is a set of ordered pairs. The independent variable in this project is the different sodas, also the x value. The dependent variable is the amount of calories it has, the y value.
The upper graph shows that when each soda only have one value of variables, it is a function, but the lower right graph shows that there could be two input, in this case, two different soda with the same name, for example, mountain dew and diet mountain dew, and they both have different calories, which makes it not a function. You can see that the upper graph passes the vertical line test but not the lower right graph.
This function has a domain which is (Mountain Dew, Citrus Blast, Pepsi, Brisk, and Sierra Mist). The range is (110, 140, 100, 80, 100) in it's chronological order based on it's domain because each soda has a specific value of calories.

Hey Karessa,

There is a domain. I'll help you with it tomorrow.
