Question

What is the domain of the function f(x)=x?

A) All real numbers R
B) All real numbers except 0
C) Positive real numbers +R +
D) Negative real numbers −R −

Answer 1

The domain of the function f(x)=x is all real numbers, as there are no restrictions on the value of x in the function.

Step-by-step explanation:

The question asks about the domain of the function f(x) = x. The domain represents all the possible input values (x-values) for which the function is defined. In this case, the function is defined for every real number, as there are no restrictions on x. Therefore, the domain of the function f(x) = x is all real numbers, denoted by ℝ.
