If we have a real-valued function , the values of will necessarily fall in the following range:
What is the value of ?
Consider two sets:
If a function is defined from to , what is the maximum possible number of such functions?
For two sets is an injective function from to . If and , what is the sum of all the elements of that can possibly be the value of ?
Given that the domain and codomain of the function are restricted to the real numbers, how many elements of the domain of are integers?
For two sets is a bijective function from to . What is the value of ?
