If `f (x) = x^(4) + 2x^(3)`, them `lim_(x to 2) (f(x) - f(2))/(x - 2)` is equal to

lim_(x rarr2)(f(x)-f(2))/(x-2)=

Let f(2) =4and f '(2) =4, then lim _(xto2)(x f(2) -2f(x))/(x-2) is equal to-

If f(2)=2 and f'(2)=1, and then lim_(x to 2) (2x^(2)-4f(x))/(x-2) is equal to

If f(a) = 2 , f ' (a) = 1 , g (a) = -1 , g'(a) = 2 , then lim_(x to a) (g (x) * f (a) - g (a) * f(x))/( x- a) is equal to

If f(4)= 4, f'(4) =1 then lim_(x to 4) 2((2-sqrtf(x))/ (2 - sqrtx)) is equal to

If f(4)= 4, f'(4) =1 then lim_(x to 4) 2((2-sqrtf(x))/ (2 - sqrtx)) is equal to

If f(2) = 4 and f^(')(2) =1 then lim_(x rarr 2) (x f(2)-2f (x))/(x-2)

If f(2) = 2 and f^(')(2) = 1 , then lim_(x rarr 2) (2x^(2)-4 f(x))/(x-2) =
