If f(x)=3x-7/5x-3 then (fof)(x)=
The domain of the function √1/cos |x| is
Consider the function f(x)=x sin(1/x),x≠0 and f(0) =0,then
If f(x)=[x], g(x)=x-[x]then which of the following functions is the zero functions
If f: R→R,, g: R→R, are defined by f(x)=4x-1, g(x)=x3+2, then gof(a+1/4)=
The domain of 1/ log(1-x) is
The function f(x) = x/√1-x2 and g(x)=x/√1+x2, find fog(x).
If f(x)=1og(cos x), then domain f.=
If f={(a, 1), (b, -2), (c, 3)}, g={(a, -2), (b, 0), (c, 1)} then f2+g2=
A={-1, 0, 1, 2}, B= {2, 3, 6,}If f from A into B defined by f(x)=x2+2, then f is
