Answer: Domain: x ≥ 0 Interval Notation: x = [0, ∞)
Step-by-step explanation:
f (x) = 3√x
There IS a restriction on x because it is inside the square root symbol.
In order for the radical to be a real number, the expression under the radical must be greater than or equal to 0. The value inside the radical is "x".
So, x ≥ 0 It is already solved for x so no further work is needed.
