Question

true or false?
_______The input of a function are the domain of the function.

______A funcation pairs every input with exactly one output.

Answer 1

Second true ( this is the definition of the function )
first one i am not native english speaker so i dont know all the english names but i believe it is also true ( if i understand the names correctly )

Answer 2

I dont know how accurate you want to be as second one doesn't have to be true, since the function
\[f(x)=\sqrt{x}\]
will not pair an output to negative values . Thus second is also false is you want to be accurate. However I believe if it is some sort of school test you can safely say yes.

Answer 3

sooo the second one is true and the first one is false?

Answer 4

I believe both are true, however i cant be sure about the first one as i dont know if i undestrand all the expressions , and the second one is debateable , however ganerally assumed to be true
