Passage / Comprehension

A function $f (x)$ is said to be even if $f (- x) = f (x)$ and odd if $f (- x) = - f (x)$ . Also, $f (x)$ is said to be periodic if $f (x + T) = f (x)$ for $T > 0$ , and the least positive value $T$ is called its period.

$f (x)$ is an even polynomial function . Then $sin (f (x) - 3 x)$ is

Options:

Answer:

Solution:

Let $g (x) = sin [f (x) - 3 x]$ $g (- x) = sin [f (- x) + 3 x] = sin [f (x) + 3 x]$
