Which of the following describes all values of x for which 25–x^2 >= 0? Choose the correct choice from the following: A) x >= 1 B) x <= –1 C) 0 <= x <= 1 D) x <= –1 or x >= 1 E) –5 <= x <= 5
25 - x^2 &gt;=0   means x^2 - 25 &lt;=0   =&gt; (x-5)(x+5) &lt;= 0   =&gt; -5 &lt;= x &lt;= 5   Answer - –5 &lt;= x &lt;= 5
<result>E</result>
