What is the domain of f (x) = 3x - 2? x > 0 x x x is a real number

Option (4). x is a real number

Step-by-step explanation:

Domain of any function is defined by the x values (Input values) and range by the y-values (Output values).

Given function is f (x) = 3x - 2

When we graph this function, we get a straight line.

That means the given function is defined for all real numbers.

Therefore, domain of this function will be all real numbers.

Domain: x is a real number

Option (4) will be the answer.
