1.Relation and Function
hard

વિધેય $y = f(x)$ નો આલેખ $x = 2$ ને સમિત હોય તો

A

$f(x) = - f( - x)$

B

$f(2 + x) = f(2 - x)$

C

$f(x) = f( - x)$

D

$f(x + 2) = f(x - 2)$

(AIEEE-2004)

Solution

(b) $f(x) = f( – x) \Rightarrow f(0 + x) = f(0 – x)$ is symmetrical about $x = 0$.

$\therefore $ $f(2 + x) = f(2 – x)$ is symmetrical about $x = 2$.
