Answers:
Domain = {-1, 2, 1, 8, 9}
Range = {2, 51, 3, 22}
==================================
Explanation:
The domain is the set of allowed inputs of a function. So it's the set of possible x values. We simply list the x coordinates of each point to form the domain.
The range is the set of possible y values or y outputs. So we simply list the y coordinates of the points. We toss out any duplicates. Since order doesn't matter in a set, we can have the values listed any way we want.
Side notes:
- This is a function since we don't have any repeated x values between any of the points. This graph passes the vertical line test.
- This function is not one-to-one because we have y = 51 correspond to multiple x values (x = 2 and x = 9 simultaneously). This graph fails the horizontal line test.

Let the number of apples in a bag be x apples. Basically its assigning a letter (variable) to an unknown quantity.
The phrase in the question can be written as
2x / 19 where x is a variable. 2x means '2 times x'.
Answer:
