Let M1f(x,y):`= {3} over {4}f(x+y)- {1} over {4}f(-x-y)+ { 1} over {4 }f(x-y)+ { 1} over {4 }f(y-x)-f(x)-f(y), M2f(x,y) : =2f( {x+y} over {2} )+f( {x-y} over {2} )+f( { y-x} over {2} )-f(x)-f(y). Using the direct method, we prove the Hyers-Ulam stability of the additive-quadratic p-functional inequalities (0.1) N(M1f(x,y))-pM2f(x,y,t) GEQ {t} over {t+p(x,y)} and(0.2)`N(M2f(x,y))-pM1f(x,y),t GEQ {t+p(x,y)} over {t}in fuzzy Banach spaces, where p is a fixed real number with p 6= 1.
