Answer:
Function
Step-by-step explanation:
This is a function.
The rule of a function is that every input has one output.
What that means is that for every x value, there is only one y value.
You can test this with the vertical lines method. If you draw vertical lines through the function, each vertical line should only intersect with the graph at a single point. If it intersects at two, it is not a function.

Answer:
1. -15
2. 3
3. -15
3
4. Kindly refer to the attached image.
5. -45, This change represents that achieving the goal will reduced the time by 45 seconds.
Step-by-step explanation:
Given that it is a 5 kilometre race.
Time to be reduced each month = 15 seconds
Total number of months left in the race = 3
1. Riley wants to achieve each month a decrease of 15 seconds.
Integer representing the change = <em>-15</em>
<em></em>
2. Change in time i.e. 3 months is represented by integer <em>3.</em>
<em></em>
3. There are a total of 3 months and there is a decrease of 15 every month.
so, multiplication expression is: -15
3
4. Kindly refer to the attached image for the number line representation of the answer.
The arrow is from 0 to -45.
5. Total change in time is -45.
This change represents that achieving the goal will reduced the time by 45 seconds.
