Find the Domain square root of w+4=9

Problem

√(,w+4)=9

Solution

1. Identify the restriction for the square root function. For the expression √(,w+4) to be defined in the set of real numbers, the radicand (the expression inside the square root) must be greater than or equal to zero.

2. Set up the inequality based on the radicand.

w+4≥0

3. Solve the inequality for w by subtracting 4 from both sides.

w≥−4

4. Express the domain in interval notation. The values of w start at −4 (inclusive) and extend to infinity.

[−4,∞)

Final Answer

Domain: *w∈[−4,∞)
