Depending on the values of 'r', 't', and 'e', the numerical value of that expression
might have many factors.
For example, if it happens that r=5, t=1, and e=4 for an instant, then, just
for a moment, (r + t)(e) = (5+1)(4) = 24, and the factors of (r+t)(e) are
1, 2, 3, 4, 6, 8, 12, and 24 . But that's only a temporary situation.
The only factors of (r+t)(e) that don't depend on the values of 'r', 't', or 'e' ,
and are always good, are (<em>r + t</em>) and (<em>e</em>) .
Answer:

Step-by-step explanation:
Given: See the attached image
To find: the function represented by the table
Solution:
A function is a relation in which every element of the domain has a unique image in the co-domain.

Here,
are elements in the domain and
are elements in the co-domain.
Therefore, the table represents the function 
Yes because the the x value is not repeated. It can not be a function if the arrow in one of the x values is pointing to more than one y value.
