Mr. Estrada I get it, but my question is when you say it must take up all real number your mean the whole y-values of the graph right?
Also can it be one to one even if the line doesnt go threw the whole graph ?

Yes, the real numbers part is in regards to y-values.
Also what do you mean by "If the line doesnt go threw the whole graph"?

Mr. Estrada I didn't really understand how to determine if the function is onto, I didn't get what you meant by all real numbers
