Answer:
Data Set 1 and 3.
Step-by-step explanation:
For a table to be a function, there cannot be multiple x values of the same number. This means that a function must be one-to-one.
When looking at the data sets, we can eliminate them by using this logic. Data Set 2 contains two y values at y = 6, as well as two x values at x = 1. Therefore, this is not a function.
Data Set 1 is the only table that represents a function because it consists of different x values without any repeating.
Data Set 3 also contains different x values without repetition. Each x value has a specific y value. This is a function as well.

Answer: 8 batches
Step-by-step explanation:
To get the number of batches she made, we can just use proportion to solve it. But first, we need to convert 5 1/3 to improper fraction
5 1/3 = 16/3
Then we can now use the proportion to solve
2/3 cups = 1 batch
16/3 cups = x (note:5 1/3=16/3)
cross multiply
2/3 × x = 16 /3
2x/ 3 = 16/3
we need to make x the subject of the formula, to do that we will multiply each side of the equation by 3/2
2/3 × 3/2 x = 16/3 × 3/2
6x /6 = 48 / 6
x = 8
Therefore she made 8 batches of cookies.

Step-by-step explanation:
Given the function
and its domain , its range is
The domain of a function is the set of all possible values that we can input to the function.
The range of a function is the set of all possible values that a function can output.
For the function
if the domain is the set , we can get the range by substituting each value in the domain into the function. The resulting set of values gives the range of the function.
The range will then be
