Answer 5

A function has an input and only one output.

Answer 6

Ok so we can take out the second one right?

Answer 7

Yes

Answer 8

One type of function would be a linear function: y=mx + b

Answer 9

Don't get fooled by the plus sign because if b is a negative integer, then it would be like y=mx + (-b) or y=mx - b. It means the same thing.
