Find the values of k so that the function f is continuous at the indicated point in Exercises 26 to 29.


It is given that

Also, it is given that function f is continuous at x = 5,


So, if f is defined at x = 5 and if the value of the f at x = 5 equals the limit of f at x = 5.


We can see that f is defined at x = 5 and


f(5) = kx + 1 = 5k + 1




5k + 1 = 15 -5 = 5k + 1


5k + 1 = 10


5k = 9


k =


Therefore, the required value of k is.
