Find the Domain square root of 4x+40-12=0

Problem

√(,4*x+40)−12=0

Solution

1. Identify the expression inside the square root, which is 4*x+40

2. Apply the rule for the domain of a square root function, which requires the radicand (the expression inside the root) to be greater than or equal to zero.

4*x+40≥0

3. Subtract 40 from both sides of the inequality to isolate the term with x

4*x≥−40

4. Divide both sides by 4 to solve for x

x≥−10

5. Express the domain in interval notation based on the inequality.

[−10,∞)

Final Answer

Domain:[−10,∞)
