Question

Choose the best definition for domain.

1. The inputs of a relation.

2. The outputs of a relation.

3. The movement of a graph either vertically or horizontally.

4. A special relation where every input has only one output.

Answer 1

A. The inputs of a relation

Answer 2

I like to think of the domain and range as coordinates, so think of the domain as the x value, or the input, and the range as the y value, or the output.

So, b wouldn't work because of what I just explained.

C could be defined as slope.

And d won't work because this would be defined as a function.

So the only answer left would be A. The inputs of a relation (but just know that domain is also the input of a function)

I hope I helped!
