f(x) = x^{2} is a continuous function on the set R of real numbers, and (-1, 1) is an open set in R, but f(-1, 1) = [0, 1), and [0, 1) is not an open set in R. So, f is not an open function on R.

The sum of the set of numbers divided by the amount of numbers.

The set of counting numbers greater than one.

The set of complex numbers includes the set of real numbers.

Yes.

The mean is the average of a set of numbers Mean/average = sum of the numbers in the set divided by the amount of numbers in the set

That means to add all the numbers together.

mean means the average or all the numbers in the set added together and then divided by the number of numbers in the set of numbers.

Yes. If its irrational it just means that it continues forever with no real pattern. It can still have real numbers

Countably infinite means you can set up a one-to-one correspondence between the set in question and the set of natural numbers. It can be shown that no such relationship can be established between the set of real numbers and the natural numbers, thus the set of real numbers is not "countable", but it is infinite.

The integers are the set { ...,-3,-2,-1,0,1,2,3,...} where the ... means that the list continues forever. Since this set includes the negative numbers whihc are not whole numbers, the answer would be no. The whole numbers are the set {0,1,2,3,...}

If you mean for a set of numbers in maths then it means the difference between the highest and lowest numbers.

Range means finding the difference between the highest number in a set of numbers and the lowest. Mean means dividing the total of a set of numbers by the number of numbers there are Mode means the most frequent number. Median is the number in the middle. To find the median you have to first order the numbers from lowest to highest.

No, it is not.
