Web12 jul. 2024 · Find the domain of each function: f(x) = 2√x + 4 g(x) = 3 6 − 3x Solution a) Since we cannot take the square root of a negative number, we need the inside of the square root to be non-negative. x + 4 ≥ 0 when x ≥ − 4. The domain of f(x) is [ − 4, ∞). b) We cannot divide by zero, so we need the denominator to be non-zero. WebIn Functions and Function Notation, we were introduced to the concepts of domain and range. In this section we will practice determining domains and ranges for specific functions.
