An illustration of the letter 'A' in a speech bubbles

What is the domain for `f(x) = x^2 + 2` ?

The domain of a function is the set of all possible inputs for which the function is defined.

Notice, that there does not exist any value for x which we could substitute.

Therefore, the domain of the function is the set of all real numbers.

Domain is `(-oo,oo)`
