Examine the following functions for continuity: (c) f(x) = (x^(2) - 25)/(x +5), x != -5

Examin the following functions for continuity. f(x)= (x^(2)-25)/(x+5), x ne -5 .

Simplify (x^(2)-5)(x+5)+25

If f(x)={((x^(2)-25)/(x-5)" , "xne5),(k" , "x=5):} is continuous at x=5, then k is equal to:

Simplify. (x^2 -5) (x+5) + 25

Simplify : (x^2 – 5) (x + 5) + 25
