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

If f(x)=x³-x, g(x)=sin 2x, then
