The function f(x) = 1/3x - 15 is a linear function. The domain of a linear function is all real numbers except for any values that would make the denominator zero (since division by zero is undefined).
To find the values that would make the denominator zero, set the denominator equal to zero and solve for x:
3x - 15 = 0
3x = 15
x = 5
Therefore, the function is undefined when x = 5.
The domain of the function is all real numbers except x = 5. In interval notation, this can be written as:
(-∞, 5) U (5, ∞)
