question 221

Multiple Choice

Use the quadratic formula or graphing methods to
- $$9 x ^ { 2 } \geq 3 - 3 x$$

• A) \(x \leq \frac { - 1 - \sqrt { 13 } } { 6 } \approx - 0.768\)
• B) \(\frac { - 1 - \sqrt { 13 } } { 6 } \approx - 0.768 \leq x \leq \frac { - 1 + \sqrt { 13 } } { 6 } \approx 0.434\)
• C) \(x \geq \frac { - 1 + \sqrt { 13 } } { 6 } \approx 0.434\)
• D) \(x \leq \frac { - 1 - \sqrt { 13 } } { 6 } \approx - 0.768\) or \(x \geq \frac { - 1 + \sqrt { 13 } } { 6 } \approx 0.434\)
