Let `A={u,v,w,x}`. A bijective function `f:A rarr A` is chosen at random, then the probability that `f(u)!=u,f(v)!=v,f(w)!=w` and `f(x)!=x` is

Let A={x,y,z}=B={u,v,w) and f:A to B be defined by f (x)=u, f(y)=v, f(z)=w . Then, f is

Let A = {x, y, z), B = {u, v, w} and f : A rarr B be defined by f(x) = u, f(y) = v, f(z) = w. Then, f is

If u : v : w = 3 : 6 : 8, then what will be the ratio of (u/v) : (v/w) : (w/u)?

Let A={a ,\ b ,\ c} , B={u\ v ,\ w} and let f and g be two functions from A to B and from B to A respectively defined as: f={(a ,\ v), (b ,\ u),\ (c ,\ w)} , g={(u ,\ b),\ (v ,\ a),\ (w ,\ c)}dot Show that f and g both are bijections and find fog and gofdot

If f(x)=(u)/(v) then f'(x)=(1)/(v^(3))

Let W = N cup {0} . Suppose f : W to W is a function such that f(0)=0, f(1) = 1,f(2) =2 and f(x) = f(x-2) + f(x-3) for x=3,4,……….. Then f(9) =……………..

If f and g are the function whose graphs are as shown, let u(x)=f(g(x)),w(x)=g(g(x)) Then the value of u'(1)+w'(1) is

Let f:W rarr W be a given function satisfying f(x)=f(x-1)+f(x-2) for x<=2. If f(0)=0 and f(1)=1, ther find the value of f(2)+f(3)+f(4)+f(5)+f(6)
