f(x) = x - 3
g(x) = √(3x - 4)
(f/g)(x) = (x - 3) / √(3x - 4)
(f - g)(x) = (x - 3) - √(3x - 4)
Theorems
To determine the domain of a function with a square root, set the expression inside the square root to be greater than or equal to zero: 3x - 4 ≥ 0.
To find the domain of a rational function, ensure the denominator is not zero: √(3x - 4) ≠ 0.
