Answer:
D
Step-by-step explanation:
For it to be a function, every x value must have 1 unique y value ONLY.
In option A, you can see that the x value of 1 has 2 y values, 1 & 5. So it's not a function.
In option B, you can see that the x value of 0 has 2 y values, 0 & -4. Moreover, the x value of 4 also has 2 y values, 2 & -2. So it's not a function.
In option C, you can see that the x value of -2 has 2 y values, 4 & -4. This is not a function as well.
In option D, each x value has a unique y value that are different. So this is a function.
Answer is option D.

Answer:
y = -3x +9
Step-by-step explanation:
Say x=5.764---
Then 1000x=5764.764---
Then 1000x-x = 5759
So 999x = 5759
So x=5759/999
I don't see how b can be 0 in this case... what does that mean? You would never divide by 0 and live to tell about it, right?
Answer:
Step-by-step explanation:
Yes. The commutative property of addition (as well as the commutative property of multiplication) applies to all real numbers, and even to complex numbers. As an example (for integers):
5 + (-3) = (-3) + 5
