Square Root Inequalities Concepts

This video tutorial explains how to solve square root inequalities by isolating the square root, squaring both sides, and solving the resulting inequality. It emphasizes the importance of considering the domain to avoid non-real solutions. The tutorial includes examples of simple inequalities and provides guidance on limiting solution sets based on domain constraints. Viewers are encouraged to explore more complex examples in a subsequent lesson.

What is the first step in solving square root inequalities?

• Subtract a constant from both sides

• Isolate the square root

• Add a constant to both sides

• Multiply both sides by a constant

How do square root inequalities differ from square root equations?

• They need consideration of the domain

• They are solved using logarithms

• They involve squaring both sides

• They require isolating the variable

What should be done after isolating the square root in an inequality?

• Add a constant to both sides

• Square both sides

• Take the logarithm of both sides

• Divide both sides by a constant

Why is it important to consider the domain when solving square root inequalities?

• To make the inequality linear

• To simplify the inequality

• To avoid negative numbers under the square root

• To ensure the solution is a whole number

What is the domain condition for the expression x + 7 under a square root?

• x + 7 > 0

• x + 7 ≥ 0

• x + 7 ≤ 0

• x + 7 < 0

In Example 1, what is the solution to the inequality after considering the domain?

• x > 2

• x < 2

• x ≥ 2

• x ≤ 2

What is the domain condition for the expression x - 4 under a square root?

• x - 4 < 0

• x - 4 > 0

In Example 2, what is the final solution to the inequality after considering the domain?

• 4 ≤ x ≤ 29

• x ≤ 29

• x > 29

• x ≥ 4
