Using the calculator:

To the nearest tenth:
We know that functions are mathematical entities that assign unique outputs to given inputs. In other words, a function can't have repeated values in the input repeated x-value.
For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.
We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.
Answer:

Step-by-step explanation:
The question says she used
of it, so she probably used
of it. I'm assuming this is an error in the question, and it should be asking how much is left. To solve for that:
- 
make denominators equal
