1.Non-Numeric function
Non-Numeric function is a function need not involve numbers. An example of a function that does not use numbers is the function that assigns to each nation its capital.
example: .
In the example given, the function, does not yield exactly one output per input.
= and are

for the input "." Generally a nation has only capital (at a time).
2.
give an example of a graph of a function that is a one-to-one function:
the function maps from exactly one value in the domain to each value in the range
example: the function is an example of a one-to-one function

3.
give an example of a graph of a function that is not a one-to-one function:
If a horizontal line intersects the graph of f in more than one place, then f is not one-to-one and fails the horizontal line test.
