what is the domain for f(x)=x^2+2
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)`
The function f(x) is defined as f(x)=x^2+2. The domain of a function f(x) is the set of values that x can take for which f(x) is real and defined.
For f(x) = x^2 + 2, the term x^2 is real and defined for all real values of x. The same is the case with 2
As a result the domain of the function f(x)=x^2+2 is the set of real numbers R.
