It is a relationship from one set to another, which is not a function.
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.
some real world problems have more than one answer (output) given one input, these situations can be described by functions
False
One output for each input
No. If an input in a function had more than one output, that would be a mapping, but not a function.
No. A function has only one output per input.
By definition. If one input has more than one outputs then it is 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...).
false
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.

More input results in less output. The function is inversely proportional.

The first one, which we often called SISO, is an open loop system because it has only one input and one output signal. But the later -MIMO- has more than one input and can has also more than one output.So the feedback systems are classified as MIMO because the feedback signal is considered as another input.Note: We can't use transfer function for MIMO systems.Eng.Ahmed Gendeya
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.
I'm guessing that you want to know why a TV needs more than one HDMI input. You could have one HD input from your cable or satellite provider, and then you might have another HD input from your DVD or BlueRay player.
