Solving Square Root Inequalities

• (-1, 15]

• [-1, 15]

• (-1, 15)

For a square root inequality equation, you must first​ (a)   and then solve ​ (b)   equations: one of them is the original equation, and the other is the part under the radical set greater than or equal to ​ (c)   .

• isolate the radical

• two

• zero

• three

• square both sides

3 + √(3x+12) ≤ 9

• [-4,8]

• (- ∞, 8]

• [-4,-2]

• [4,6]

Which value of x makes the inequality true? 2√x < 1

• 4/9

• 1/4

• 0.38

• 0.14

• [6,∞)

• (-∞,22)

• [6, 22)

• (22, ∞)

• [6,10]

The value of √k lies between 2.2 and 2.3. Select all possible values of k.
