Write the Interval in Set-Builder Notation and Graph the Set $$\left[ - 6 , \frac { 1 } { 4 } \right]$$

Write the interval in set-builder notation and graph the set on a number line.
- $$\left[ - 6 , \frac { 1 } { 4 } \right]$$

A) $\left\{ x \mid - 6 \leq x \leq \frac { 1 } { 4 } \right\}$

B) $\left\{ x \mid - 6 < x < \frac { 1 } { 4 } \right\}$

C) $\left\{ x \mid - 6 \leq x \leq \frac { 1 } { 4 } \right\}$

D) $\left\{ x \mid - 6 \leq x \leq \frac { 1 } { 4 } \right\}$
