Question 2 What is wrong with the argument claiming to prove the following assertion. You should not only find the error, but explain why it is an error providing an example. Assertion: For any two numbers a and 3 define max(a. 3) to be the largest of a er 3. If f and g are continuous at: then so is the function max(f.9) defined by max(f.g)(x) = max(f(r).g(z)). Proof: According to Definition 2.4.1 it must be shown that lim max(f.g)(x) = max(f.g)(=). According to Definition 2.2.1, in order to show this, it must be shown that for every > 0 there is some 6>0 such that max(f.g)(x)-max(f.g)(=) < whenever 0 0 be arbitrary. By the definition of max(f.g)(=)= max(f(=).g(=)) it must be the case that either max(f.g)(=) = f(=) or max(f.g)(=) = g(=) Only the first case will be considered since the argument in the second case is identical. If max (f. 9) (=) = f(=) then there must be some non-empty interval (=-p.=+p) such that max (f.g)(x) = f(x) (1) Juris Steprins 2022.

(One of the errors is an error of logic, while the other error is more of a typo.) Assertion: Let p>0. Suppose that for all z such that 0
