In this collection there is a number of questions: True or false? or Is it possible? Give a proof or an example in each case. Is it possible?

a) f is continuous at x0, g is not continuous at x0, and f + g is continuous at x0;

b) f and g are not continuous at x0, and f + g is continuous at x0; 2

c) f is continuous at x0, g is not continuous at x0, and f · g is continuous at x0;
