What is the output mapping x 3x use the input 5?
15
What is an expression that describes the relationshipbetween each input and output?
A mapping. It need not be a function.
What is an input or output relation that has exactly one output for each input?
A one-to-one function, a.k.a. an injective function.
Can an input in a function have more than one output?
No. If an input in a function had more than one output, that would be a mapping, but not a function.
What the set of the x values also known as domain?
A function, f, is usually a mapping from a set of input values. This set, whose elements are often denoted by x, is called the domain.A function, f, is usually a mapping from a set of input values.

What is the mapping between a set of input and a set of output?
It is simply a mapping. It could be a function but there are several conditions that need to be met before the mapping can become a function and there is no basis for assuming that those conditions are met.
What is a relation with the property that for each input there is exactly one output?
That's a proper function, a conformal mapping, etc.
What is the difference between input and output?
The differnce between input and output is input=in output=out The differnce between input and output is input=in output=out
What is a ratio that compares the difference between two output values to the difference between the corresponding input values?
something
How do you describe the domain and range of a function?
The domain is the set of values of the input while the range is the set of output values.
If a given input value yields four output values that relationship can be best described as a relation true or false?
This is true. If a given input value yields four output values that relationship can be best described as a relation.
What is a zero of a function?
A function maps "input" values to "output" values. A zero of a function is any "input" value that will map to an "output" value of zero. For example, a value of "x" for which the equation f(x) = 0 is true.
