A function f(x) assigns a value f(x) to each x. The count cuts the y-axis at the point (0, f(0)). If there is a second intersection, f(0) would no longer be clearly defined. f(x) would not be a function.

Yes.

Next comes also “The x axis cuts the y axis at most once. Right or wrong?”

Joa is correct because otherwise it is no longer a function by definition.

ANNEX In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.

From Wikipedia

That’s usually correct. A function is a Relationshipwhich one or more inputs only one edition order. Since the input per x unit is displayed, there can be only one y value per x unit, the output.

Only then, if the Y axis does not describe the output (mit-) but represents the input variable, it can be different, e.g.

As a rule, however, the y dimension describes the or one of the expenditures, so it is correct.

It’s not a function.

What are you doing?

Yes, that’s true, since the definition of a function includes that each x worth only one y. If this is not the case, it is not a function graph

Right
