If `f(1+x)=x^(2)+1` then `f(2-h)` is

If f(x)=x^2+2x+1 , then: f(x-1)-=

If f (x)=4x -x ^(2), then f (a+1) -f (a-1) =

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

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

If 2f (x +1) +f ((1)/( x +1))=2x, then f(2) is equal to

If f(2x + 1 ) = x + 1 , then f(x^2) =

f(x)+f(1-x)=2, then f((1)/(2)) is

(1) If f(x) = sqrt(x) , prove that : (f(x + h) - f(x))/(h) = (1)/(sqrt(x + h) + sqrtx) . (2) If f(x) = x^(2) , find : (f(1.1) - f(1))/(1.1 - 1) .

If f(x)=log((1+x)/(1-x)), then f(x) is (i) Even Function (ii) f(x_(1))-f(x_(2))=f(x_(1)+x_(2)) (iii) ((f(x_(1)))/(f(x_(2))))=f(x_(1)-x_(2)) (iv) Odd function
