A relation is defined as a function if each input (or domain element) is associated with exactly one output (or range element). In a one-to-many relationship, a single input is linked to multiple outputs, which violates the definition of a function. Therefore, since a function must have a unique output for every input, a one-to-many relationship cannot be classified as a function.
a function is a one-to-one and many-to one relation
1. One to One -function- 2. One to Many -relation- 3. Many to Many -function-
A function is a relationship that is one-to-one or many-to-one but not one-to-many. Thus, if a and b are in the domain of the function, then their images in the range, f(a) and f(b) MUST be equal.
It is a surjection.
A many-to-one function is a type of function where multiple input values can map to the same output value. In contrast, a one-to-one function (or injective function) ensures that each input value maps to a unique output value, meaning no two different inputs share the same output. Thus, in a one-to-one function, every output corresponds to exactly one input, while in a many-to-one function, one output can correspond to several inputs. This distinction is crucial in understanding the behavior and properties of functions in mathematics.

No. By definition, f(-x) = f(x) so that it is many-to-one.
For an algebraic function in one variable, as many as the highest power of the variable.

No. If the function has more than one x-intercept then there are more than one values of x for which y = 0. This means that, for the inverse function, y = 0 should be mapped onto more than one x values. That is, the inverse function would be many-to-one. But a function cannot be many-to-one. So the "inverse" is not a function. And tat means the original function is not invertible.

Any graph of a mapping which is one-to-one or many-to-one but not one-to-many.
One function. A enzyme is particular about it's substrate, so the enzyme can catalyze one reaction by lowering that reaction's activation energy.
