find fog and gof where f(x)= modx+x and g(x)= modx-x for all x belongs to R

fog= f(g(x))
= f( modx - x)
= mod( modx - x)
  • -37
f(x) = |x| +x and g(x) = |x| - x So, fog = f(g(x)) = f(|x| - x) = | |x| - x | + (|x| - x) gof = g(f(x)) = g((|x| + x) = | |x| + x | - (|x| + x)

similarly u can find gof(x)

similarly you can get gof(x) =0
