25 ! the designer of a role-playing game uses a function, p(x), to determine the minimum number of experience points a player needs in order to unlock chapter x of an adventure. select the appropriate domain for this situation. a. the set of all real numbers b. the set of all positive real numbers c. the set of all positive integers d. the set of all integers will mark brainliest

The appropriate domain for this situation.C.  The set of all positive integers

Numbers in mathematics can be divided into several terms

Real numbers include Whole Numbers (0,1,2..),Rational Numbers(numbers that can be expressed in simple fractions), or Irrational Numbers(√3,π, etc)

Integer  consist of positive, negative and 0 numbers

A role-playing game have experience points of a player for every chapter.

So the chapter must be in number 1,2,3 .. etc

Domain is the input of a function

for the function P(x), x = domain

Then the appropriate domain for this situation :

C.  the set of all positive integers

It is not possible to choose points A, B, or D because they can be negative or fractional

the set of ordered pairs of functions
