Question

Are all the following true:

A sequence is a function whose domain is the set of real numbers.

The horizontal line test may be used to determine whether a function is one-to-one.

A function is a relation in which each value of the input variable is paired with exactly one value of the output variable.

I say yes

Answer 1

Ooh yeah it's aum!

Answer 2

The domain of a sequence is usually the counting numbers 1, 2, 3, etc.

It is true that the horizontal line test may be used to determine whether a function is one-to-one.

It is true that a function is a relation in which each value of the input variable is paired with exactly one value of the output variable.

Answer 3

Ah, so the first one is wrong?

Answer 4

Yes. The domain is not all real numbers because the domain refers to the nth term of a sequence where n refers to the first, second, third, etc. term of a sequence.
