Find an upper bound for each of the following quantities. Please be practical! You don't need to find the exact value, just some number (might as well be an integer) that is (definitely) larger! Please write full sentences to justify how you know that your answer is (definitely) larger. (No credit is given for just saying "a trillion billion zillion", unless you justify your reasoning.) (a) 2020c +(13 x 10) (b) sin(422)-2 on the interval (-3,3]. (e) (sin(4x2))] on the interval [-3,3]. (d) 4(3+) cos(-2) on the interval (-1,3].
