Question

( 2 frac{sqrt{-frac{n}{2}}-frac{2}{2}}{frac{1}{4}} )
( f(x)=frac{1}{x}=frac{1}{x}, 0,13 )
( f(x+1)=frac{1}{x+1} )
( f(x-1)=frac{1}{x} )
( f(x+1)-f(x-1) )
( =frac{1}{x+1}-frac{1}{x-1} )
( frac{x-1-x-1}{x^{2}-1} )
( frac{2}{1-x^{2}}+sin x )

# / જો f (x) = હોય જયાં x c Z - {– 1, 0, 1} તો સાબિત કરો કે _f(x + 1) - f (x – 1) – 1 12
