Exercise 3 - Continuity of polynomials [15 points). Polynomials are known to be continuous functions on their domain of definition. Consider P(x) = x2 - x and show that it is a continuous function based on the definitions provided in the lecture notes. Exercise 4 - Binary operations (10 points). In a purely binary base (all quantities below are binary numbers), perform the following operations: 11011 . 101/1001 1101 + 110 101011 111111 1011 x 111 Precisely detail your steps
