If f(x+1/x)=x^2+1/x^2+8 then f(3), f(5), f(-1)

Let f be two differentiable function satisfying f(1)=1,f(2)=4, f(3)=9 , then

Let f be two differentiable function satisfying f(1)=1,f(2)=4, f(3)=9 , then

If f(x) is a polynomial of least degree such that f(1)=1,f(2)=(1)/(2),f(3)=(1)/(3),f(4)=(1)/(4) then f(5)=

Let A={-1, 0, 1} and B = {1, 2, 3, 4}. If f is the rule associating elements of A to elements of B, such that f(-1) = 2, f(0) = 1 and f(1) = 4. Does f define a mapping?

If f:NtoR is defined by f(1) = - 1 and f(n+1) = 3f(n) + 2 for nge1 , then f is
