f(x) = |x|. If f(x) is reflected with respect to the line x -2 =0 to get g(x), then which of the following is g(x)?
Options:
A .  g(x+4) = |x|
B .  g(x-4) = |x|
C .  g(x) = |x| - 2
D .  g(x) = |x| + 2
E .  None of these
Answer: Option A : A Option (a) g(4) = 0 also f(0) = 0. So, g(4) = f(0) Out of the given options, only (a) satisfies g(4) = f(0) when you put x = 0 Hence, the answer is option (a)
