1. Is there a pattern in the data points? If so, describe the pattern.
2. Do the points show a positive linear association, a positive nonlinear association, a negative linear association, a negative nonlinear association, or no association?
3. What does this association tell you about the relationship between the variables?
4. Are there any clusters or outliers?

1. No pattern 2. negative nonlinear 3. Variables don't seem related 4. many outliers

Step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
