Answer:

Step-by-step explanation:
This question is asking you to insert two equations, f(x) and g(x), into the equation g(x) - f(x). This will lead to the equation below.

Now we can solve for the equation.

Answer:
I only
Step-by-step explanaition:
The domain (x) can not repeat in order for it to be a function.
Answer:
y=-x-5
Step-by-step explanation:
Slope is the x, since slope is equal to -1, x=-1. For the y intercept you simply add or subtract the number given to you, since it is -5 you would add a -5 to the end of the equation
Slope =

------------------------
6 - 6 = 0
15 - (-1) = 16
0 / 16 = 0
--------------------------------
You have a
slope of 0, meaning that this is a straight horizontal line
