In its simplest form the domain is all the values that go into a function, and a range is all the values that come out.
I think it is B because it has a continuous line soy it couldn’t be a. It has negative numbers so it couldn’t be D. And it has negative numbers so couldn’t be C
Answer:
Step-by-step explanation:
The answer is c.
Proportional means a relationship of y = a constant multiplied by x
In this case, the constant is 7.
i.e. y = 7x
So if
x is 3, y is 21
x is 5, y is 35
x is 7, y is 49
and so on...
And there you have it.
