D. (fog)(x)
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
If f(x)= (a-xn)1/n, where a>0 and n?N, then (fof)(x)=
If f(x)=αx+β and f={(1, 1), (2,3), (3,5), (4, 7)} then the values of α, β are
If y=x2+2x+1/x2+2x+7, then inverse function x is defined only when
