Plot several points , and deduce the respresentation .

Zero can't be , the domain is R*.

Helolo, tamiatha!

I would like to see your teacher's answer . . . and his/her explanation.

$\displaystyle \text{identify the function represented by: }\: y\:=\:\frac{3}{x}$

My answer: hyperbola

My teacher says i am wrong. .? ?

The instruction "Identify the function" is rather vague . . . What does it mean?

Are we to describe the relationship between $\displaystyle x$ and $\displaystyle y$ ?
. . Is this an essay question?
If so, we could say: "$\displaystyle y$ is inversely proportional to $\displaystyle x$."

If we are to identity the graph of the equation, your answer is correct.

… Zero can't be …

I think you mean 3/0 can't be.

I know that 0 can be, since I see it all around me every day.

Is R* standard notation for R\{0} ?

I'm not sure that I've seen the notation R* before.

You would have been exactly correct:

If the question had asked:

identify the graph, represented by the function represented by y=3/x

and your answer was:

rectangular hyperbola

Aside from that I agree with Soroban regarding vagueness of the question.
