What is the domain of f(x) = 3x – 2?

Answer
A
{x | x > 0}
B
{x | x < 0}
C
{x | x = 0}
D
{x | x is a real number}

Explanation

The function f(x) = 3x − 2 uses only multiplication and subtraction, which are defined for every real number x. There are no restrictions such as a denominator that could be zero or a square root of a negative number. Therefore, the domain is all real numbers, choice D.
