If `f(x) = x^3 - kx + 7` is maximum at `x = -1,` then find the value of `k.`

If the function f(x) = x^(3)-24x^(2)+6kx-8 is maximum at x = 2 then find value of k.

If the function f(x) = x^(3)-24x^(2)+6kx-8 is maximum at x = 2 then find value of k.

(v) If f(x)={ kx^(2) x>=1 4 x<1 is continuous at x=1 then the value of k is:

If f(x) = (kx)/(x+1)(x ne -1) such that (fof(x))=x , then find the value of k. (when x ne 0 ).

Let f and g be two functions defined by f(x)=(x)/(x+1), g(x) =(x)/(1-x) . If ( f o g ) ^(-1) (x) is equal to kx, then find the value of k.

If F(x)= {(Kx^(2) if x le 2),(3 if x gt 2):} is continuous at x = 2, then the value of K is

If f(x) = {(2x+1,",",x le 1),(-3-kx^(2),",",x gt 1):} is continuous at x = 1, then the value of k is

If f(x) = {(2x+1,",",x le 1),(-3-kx^(2),",",x gt 1):} is continuous at x = 1, then the value of k is
