Find fog\ (2) and gof\ (1) when: f: R->R ; f(x)=x^2+8 and g: R->R ; g(x)=3x^3+1 .

Find fog\ (2) and gof\ (1) when: f: R->R ; f(x)=x^2+8 and g: R->R ; g(x)=3x^3+1 .

Find fog(2) and gof(1) , when f:R→R;f(x)=x^2+8 and g:R→R;g(x)=3x^3+1 .

Let :R rarr R;f(x)=sin x and g:R rarr Rg(x)=x^(2) find fog and gof.

If f:R rarr R,f(x)=2x-1 and g:R rarr R,g(x)=x^(2) then (gof)(x) equals

If the formula f : R rarr R be given by f(x) = x^2 2 and g : R rarr R be given by g(x) = (x)/(x-1). X ne 1 . Find fog and gof. Hence find (fog) (2) and (gof (-3)

Let R be the set of real numbes.If f:R rarr R;f(x)=x^(2) and g:R rarr R;g(x)=2x+1. Then,find fog and gof .Also,show that fog!= gof.

Find gof and fog if f : R rarr R and g : R rarr R are given by f(x) = cosx and g(x) = 3x^(2)

Find gof and fog, if f: R rarr R and g: R rarr R are given by f(x) = cos x and g(x) = 3x^(2) , then show that gof ne fog.

If the function f:R rarr R be given by f(x)=x^(2)+2 and g:R rarr R be given by g(x)=(x)/(x-1). Find fog and gof.
