Assume that f(1) = 0 and that for all integers m and n f(m+n) = f(m) + f(n) + 3(4mn-1) then f(19) = मान लें कि f(1)= 0 और कि सभी पूर्णांकों के लिए m और n f(m+n) = f(m)+f(m)+3(4mn-1) फिर f(19)

If f(2m+(n)/(8),2m-(n)/(8))=mn, then f(x,y)+f(y,x)=0

If f(x) =[m x^2+n , x 1 . For what integers m and n does both (lim)_(x->1)f(x)dot

Let f(1)=1 and f(n)=2 sum_(r=1)^(n-1)f(r) then sum_(n=1)^(m)f(n)=
