Determine If the Given Function Can Be Extended to a Continuous

question 75

Multiple Choice

Determine if the given function can be extended to a continuous function at x = 0. If so, approximate the extended
function's value at x = 0 (rounded to four decimal places if necessary) . If not, determine whether the function can be
continuously extended from the left or from the right and provide the values of the extended functions at x = 0.
Otherwise write "no continuous extension."
- $$f ( x ) = \frac { \cos 2 x } { | 2 x | }$$

• A) f(0) = 2 only from the left
• B) No continuous extension
• C) f(0) = 2
• D) f(0) = 2 only from the right
