Question 221

Multiple Choice

Use the quadratic formula or graphing methods to
- 9x233x9 x ^ { 2 } \geq 3 - 3 x


A) x11360.768x \leq \frac { - 1 - \sqrt { 13 } } { 6 } \approx - 0.768
B) 11360.768x1+1360.434\frac { - 1 - \sqrt { 13 } } { 6 } \approx - 0.768 \leq x \leq \frac { - 1 + \sqrt { 13 } } { 6 } \approx 0.434
C) x1+1360.434x \geq \frac { - 1 + \sqrt { 13 } } { 6 } \approx 0.434
D) x11360.768x \leq \frac { - 1 - \sqrt { 13 } } { 6 } \approx - 0.768 or x1+1360.434x \geq \frac { - 1 + \sqrt { 13 } } { 6 } \approx 0.434
