Answer:
Correct answer is the domain.
Step-by-step explanation:
A domain is the input set of a function.
A range is the output set of the function.
It is more important to know the domain of the function to be able to determine the corresponding output set so the function can be graphed. To start with the domain is very useful because every domain element has a corresponding unique output element.
Suppose you started with the range element of 9. The input set for an output of 9 is {-3,3}. This makes it hard to match up the elements. This example highlights why it is important to start with the domain rather than the range.
Answer:
y=-2x+3
Step-by-step explanation:
In a y=mx+b equation, M is the slope and B is the y intercept. So write down that equation and plug in the numbers you're given

Answer:
They used 3.14 for pi:


Step-by-step explanation:
is the volume of a sphere with radius r.
I think that is the diameter given in the picture.
The radius is half the diameter.
So the radius is 5 since the diameter is 10.
Plug in this gives you:
