Answer:
Domain: All Real Numbers
Range: All Real Numbers
Step-by-step explanation:
F is
F = {(x, y ) | x + y = 10}
(x,y) is the ordered pair
x + y = 10 is the expression
We can rearrange it
y = 10 - x
And then we can plot it using a graphing calculator. See attached image
By looking at the plot and examining the expression, we can see that there are no restrictions over x or y.
This means that the domain and range are all real numbers
Domain: All Real Numbers
Range: All Real Numbers
F is a function because it is a relation that associates each element x to a single element y.

Answer:
Look below.
Step-by-step explanation:
For one, g+g+g+g does not equal g^4. That equals g·g·g·g.
But like you said, 4g = g·g·g·g as well, so shouldn't they be equal?
The answer is more simple than you might expect:
We'll do the second one first. I don't know why, that is just how it is going to be done.
Let's assign a value to 'g'. We'll call it g = 3.
3 to the 4th power is
1) 3·3 = 9
2) 9·3 = 27
3) 27·3 = 81.
So = 81.
But, you probably figured out, with g = 3, that 4g = 12, since 3·4 = 12.
Obviously, 81 ≠ 27, meaning these are not the same, and that is the main difference.
