Yes. Typical example: y = x2. To avoid comparing infinite sets, restrict the function to integers between -3 and +3.
Domain = -3, -2 , ... , 2 , 3. So |Domain| = 7
Range = 0, 1, 4, 9 so |Range| = 4
You have a function that is many-to-one. One consequence is that, without redefining its domain, the function cannot have an inverse.
Yes.
Yes. The range can have fewer number of entries.As an extreme case, consider f(x) = 3, where x is a Real number.The domain is all Real numbers - infinitely many of them, while the range is one value: 3.A function can contain one-to-one or many-to-one relationships but one-to-many relationships are not permitted. As a result, the cardinality of the range cannot be bigger than the cardinality of the domain.

Add up all the numbers and divide by the amount of entries you added together.
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
Yes.

The smallest four prime numbers are 2, 3, 5, 7, and their sum happens to be a prime.

It is possible only because of different number of neutrons.
If you have to find a median in a set of numbers in which there are an even number of entries, you must find the average of the two numbers the come in the middle.
The Count function can be used if you are looking for just numbers and the Counta function if you are looking for numbers and text entries.
It is not possible to answer the question since there are no operators between the numbers. 80 + 600 is very different from 80 * 600!It is not possible to answer the question since there are no operators between the numbers. 80 + 600 is very different from 80 * 600!It is not possible to answer the question since there are no operators between the numbers. 80 + 600 is very different from 80 * 600!It is not possible to answer the question since there are no operators between the numbers. 80 + 600 is very different from 80 * 600!
