Question

Write the set of all real numbers between 1 and 2 in set builder form​

Answer 1

Answer:

We can write the domain of f(x) in set builder notation as, {x | x ≥ 0}. If the domain of a function is all real numbers (i.e. there are no restrictions on x), you can simply state the domain as, 'all real numbers,' or use the symbol to represent all real numbers

Answer 2

Let the set be called S.

Therefore, a set of all real numbers between 1 and 2 in set-builder form will be

S: { x ∈ R | 2 < x < 1 }

A set is a collection of a group of things or numbers.

For example: {a,b,c,d}

We can also build a set by using and adding all the conditions that will be given in the question.

{ x| x > 6}

here we can say that this set contains all the values of x which are greater than 6.

We can also use": " instead of " | " in the set.

Here in the question, we were asked to add the number that has to be real. To specify this condition in the set we have added ∈ R in the answer.
