Provide an Appropriate Response $c$ That Will Make $$f ( x ) = \left\{ \begin{array} { c c } \frac { \sin ^ { 2 } 4 x } { x ^ { 2 } } , & x \neq 0 \\c , & x = 0\end{array} \right.$$

Short Answer

Provide an appropriate response.
-Find a value of $c$ that will make
$$f ( x ) = \left\{ \begin{array} { c c } \frac { \sin ^ { 2 } 4 x } { x ^ { 2 } } , & x \neq 0 \\c , & x = 0\end{array} \right.$$
continuous at $x = 0$ .
