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...).

f(x) = x - 8.
it is possible
It is false.
No. If an input in a function had more than one output, that would be a mapping, but not a function.

By definition. If one input has more than one outputs then it is not a function.
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.
The output is 1 more than 10 times the input.

Input energy is typically more useful than output energy because input energy is the initial energy put into a system to produce the desired output. Output energy, on the other hand, is the energy produced by the system after losses and inefficiencies have occurred, so it is usually less than the input energy. By maximizing input energy efficiency, we can achieve a more effective output.
f(x) = x - 8.
Work output can never be more than work input. That's a law of nature. In the real world, it's always less.
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
Good question. A relation is simply that; any x-value to create any y-value. A function, however, cannot be defined for multiple values of x. In other words, for a relation to be a function, it must have singular values for all x within its domain.
