Answer:
No.

To be a function, each input (x value) must go to exactly one output (y value). In this instance, the input 5 has an output of -15 and 4. This breaks the rule. Therefore, this relation is not a function.
Keep Change Flip is the way to think about dividing fractions.
First- 4/6 divided by 4/12
Next- Change the division sign to multiplecation 4/6 time 4/12
Then- Flip the second number 4/6 times 12/4
Now multiply
48/24 this simplifies down to 2
Start off by finding how much the price was reduced. 225-195=30, so it was reduced by $30. This can be put into fraction form as 30/225. Now simply divide that to get about 0.1333, or about 13% when rounded to the nearest whole percentage.
