Find the value of k if nbsp nbsp f x x2 nbsp 5x 6 x 2 for x nbsp ne nbsp 2 nbsp And nbsp f 2 k is c......

And f (2) = k is continuous at x = 2. 

Explanation:

Given f(x) is continuous at x = 2  

⇒ lim f(x)= lim (x2 - 5x + 6) / (x-2) 

     x2       x 2           

   = lim (x-2) (x-3) / (x-2) 

        x2 

   = lim(x-3) = 2-3 = -1 

      x 2 

   Therefore, k = -1
