Which of the following describes all values of x for which 36–x^2 >= 0? Choose the correct choice from the following:
A) x >= 1	B) x <= –1	C) -6 <= x <= 6	D) x <= –1 or x >= 1	E) –1 <= x <= 1
36 - x^2 &gt;=0   means x^2 - 36 &lt;=0   =&gt; (x-6)(x+6) &lt;= 0   =&gt; -6 &lt;= x &lt;= 6   Answer - -6 &lt;= x &lt;= 6
<result>C</result>
