Of course. Think about a lawn sprinkler, a meat grinder,
a spaghetti machine, and a shower head.
True
some real world problems have more than one answer (output) given one input, these situations can be described by functions
False
Yes, it is possible to get more than one output number for a single input in certain mathematical contexts, such as in functions that are not well-defined or in multi-valued functions. For instance, in the case of the square root function, the input 4 can yield both +2 and -2 as outputs. This ambiguity occurs when the function does not adhere to the definition of a mathematical function, which requires that each input corresponds to exactly one output.
multiplexer
No. A function has only one output per input.
No. If an input in a function had more than one output, that would be a mapping, but not a function.
No, it is not. A function can only have one output per input. (If it has more than one, it is still maths, but it cannot be called a "function". It would probably be called an equation or a formula etc...).
By definition. If one input has more than one outputs then it is not a function.
It is possible.
