Ответ:
The domain is all real numbers greater than or equal to zero
Step-by-step explanation:
∵ f(x) = √9x
∴ The domain is all values of x ≥ 0
because if x = number less than zero it will be negative
There is no value in the real number for √-ve values
∴ The domain is all real numbers ≥ 0
Ответ:
Domain : [0, ∞) {x | x ≥ 0} (equal to 0 all real numbers greater than or equal to 0).
Step-by-step explanation:
The given function is f(x) = √9x = 3√x
For this function f(x) is defined only if x ≥ 0 because for x < 0 the function is not defined.
f(-x) = 3√(-x) which is not defined.
Therefore domain of this function is domain: [0, ∞) {x | x ≥ 0}

41 + 113 = 154
117/200 divided by 154 = 117 / (200*154) = 117/30800 or 0.0038 to 4DP
