let `f(x)=(x-1)/(2x^2-7x+5)` then

Given, f(x)=(x-1)/(2x^2-7x+5) when xne1 Find the derivative of f(x) at x=1

Given, f (x) =(x-1)/(2x^(2)-7x+5)' when x ne 1 =-(1)/(3) when x = 1 Find the derivative of f (x) at x = 1 .

If f(x)={(x-1)/(2x^(2)-7x+5), when x!=1-(1)/(3), when x=1, prove that f'(1)=-(2)/(9)

If f(x)=(x-1)/(2x^(2)-7x+5) for x!=1 and f(x)=-(1)/(3) for x=1 then f'(1)=

If f (x) = (x -1)/( 2x ^(2) - 7x + 5) for x ne 1, f (1) = (-1)/(3), find f '(1).

If f(x)={{:((x-1)/(2x^(2)-7x+5)",","for"xne1),(-(1)/(3)",","for"x=1):} then f'(1) is equal to

If f(x) ={{:((x-1)/(2x ^(2) -7x +5),"when"x ne1),(-1/3, "when" x=1):} then the value of f '(1) is-

Let f(x)=(5x+6)/(7x+9) then, f^-1(x) =?
