If `f : R to R , f (x) =x ^(3) and g: R to R , g (x) = 2x ^(2) +1,` and R is the set of real numbers then find fog(x) and gof (x).

If f : RrarrR, f(x)=x^(3) and g : RrarrR , g (x) = 2x^(2)+1 , and R is the set of real number, then find fog (x) and gof (x).

If f : R to R , f(x)=x^(2) and g(x)=2x+1 , then

If f:R to R be defined by f(x)=3x^(2)-5 and g: R to R by g(x)= (x)/(x^(2)+1). Then, gof is

If f : R rarr R, f(x) = x^(2) + 2x - 3 and g : R rarr R, g(x) = 3x - 4 then the value of fog (x) is

If f, g : R to R such that f(x) = 3 x^(2) - 2, g (x) = sin (2x) the g of =

If f(x)=sqrt(x+3) and g(x)=x^2+1 be two real functions, then find fog and gof .

Let : R->R ; f(x)=sinx and g: R->R ; g(x)=x^2 find fog and gof .

If f :R ->R , f(x)=x^3 +3 ,and g:R->R , g(x)=2x + 1 , then f^(-1)(g^(-1)(23)) equals

If f : R rarr R, f(x) = x^(2) - 5x + 4 and g : R^(+) rarr R, g(x) = log x , then the value of (gof) (2) is

If f: R to R and g: R to R be two functions defined as f(x)=2x+1 and g(x)=x^(2)-2 respectively , then find (gof) (x) and (fog) (x) and show that (fog) (x) ne (gof) (x).
