Given the function: where a, b and k are constants, show that f(x) is continuous but not differentiable at x = k Thank you to everyone who helps <3

continuous at x = k ... ... exists therefore, f(x) is continuous at x = k differentiability at x = k ... if if since the limit does not exist, f(x) is not differentiable at x = k.
thanks skeeter!
