(a) (1 point Mobius) What conditions does a function ap) need to satisfy in order to be continuous at a: : 1? Choose the BEST answer. 0 The limit of f(.7;) as :1} approaches 1 has to exist, and 1 should not be in the domain of f. O The limit of f(3:) as an approaches 1 has to exist, and its value has to be equal to f(1). The function has to be constructed as a composition, product, sum or quotient of continuous functions, and .7: : 1 must be in the domain off. 0 O The two values for f(1) have to agree. 0 The left and right limits of f (m) as a: approaches 1 have to exist, so that the limit exists. Now let a be a parameter and consider the following piecewise-defined function on domain :2: > 0: 114.38) f0\") : ln(.7;) 15|2$71|+a if$2 1 Answer the following questions about THIS function x). if0
