Use a Graphing Utility to Graph the Equation $y = \frac { 1 } { 6 } x ^ { 2 } - 6 x + 1$

Multiple Choice

Use a graphing utility to graph the equation.Use the graph to approximate the values of x that satisfy the inequality. ​
Equation: $y = \frac { 1 } { 6 } x ^ { 2 } - 6 x + 1$ ​
Inequality: $y \leq 0$ ​

A) ​ $$x \leq - 1 - \sqrt { \frac { 4 } { 27 } } , 1 - \sqrt { \frac { 4 } { 27 } } \leq x \leq 1 + \sqrt { \frac { 4 } { 27 } }$$
B) ​ $$1 - \sqrt { \frac { 4 } { 27 } } \leq \mathrm { x } \leq 1 + \sqrt { \frac { 4 } { 27 } }$$
C) ​ $$x \leq 1 - \sqrt { \frac { 4 } { 27 } } , 1 + \sqrt { \frac { 4 } { 27 } } \leq x$$
D) ​ $$x \leq - 1 - \sqrt { \frac { 4 } { 27 } } , - 1 + \sqrt { \frac { 4 } { 27 } } \leq x$$
E) ​ $$- 1 - \sqrt { \frac { 4 } { 27 } } \leq x \leq - 1 + \sqrt { \frac { 4 } { 27 } }$$
