Answer:
The first set of ordered pairs is not a function.
Step-by-step explanation:
The X value of 7 repeats, which means that it is not a function
The value of a is 
Step-by-step explanation:
<u>1. Determine the other solution of x</u>
If one value is 5 + 
then the other value is 5 -
<u>2. Use reverse technique to find the equation</u>
(5 + ) (5 - ) = 0
25 - 
+ 
- 
= 0
- + 25 = 0
<u>3. The equation is</u> - + 25 = 0
<u>4. Find the value of a</u>
a is the number with the variable 
therefore it is -
