  We approximate a fuzzy almost quadratic function by a quadratic function in a
fuzzy sense. More precisely, we establish a fuzzy Hyers--Ulam--Rassias
stability of the quadratic functional equation $f(x+y)+f(x-y)=2f(x)+2f(y)$. Our
result can be regarded as a generalization of the stability phenomenon in the
framework of normed spaces. We also prove a generalized version of fuzzy
stability of the Pexiderized quadratic functional equation
$f(x+y)+f(x-y)=2g(x)+2h(y)$.
