If f is defined for all real `xf(a+b)=f(ab),AA a,b epsilon R, f(-1//2)=-1//2`, then find `f(-311//515)`

The function f(x) is defined for all real x. If f(a+b)=f(ab) AA a " and " b " and " f(-(1)/(2))=-(1)/(2) then find the value of f(1005).

A function f(x) is defined for all real x and satisfied f(x+y)=f(xy),AA x,y. If f(1)=-1 then f(2006) equals

If f(x+y)=f(xy) AA x, y epsilon R, and f (2013) =2013 , then f(-2013) equals

Let f(x+y)-axy=f(x)+by^(2),AA x,y in R,f(1)=8,f(2)=32 , then a+b=?

If f: R to R be defined by f(x) =(1)/(x), AA x in R. Then , f is

If f :R to R is defined by f (x) =(x )/(x ^(2) +1), find f (f(2))

Let f((x+y)/(2))=(f(x)+f(y))/(2) for all real x and y If f'(0) exists and equals -1 and f(0)=1, then find f(2)

If f: R to R defined as f(x)=3x+7 , then find f^(-1)(-2)

If f:R^(+)rarr R,f(x)+3xf((1)/(x))=2(x+1), then find f(x)
