The range of f(x) = 3x + 9 is: {y|All real numbers}

How to determine the range?

The equation of the function is given as:

f(x) = 3x + 9

The above function is a linear function, and the range of a linear function is the set of all real numbers

Hence, the range of f(x) = 3x + 9 is: {y|All real numbers}
