Consider the function f(I) = 31 + 8 3r + 1' For this function, there are two important intervals: ( - 00, A) and (A, oo) where the function is undefined at A. Find A = Consider the function p(x) = 12x5 + 30r* - 30013 + 3. p(x) has inflection points at I = D, E, and F', in increasing order. Find the inflection points. Round answers to 2 decimal places, if necessary. Consider the function f(x) = 5(x - 4)2/3. For this function there are two important intervals: ( - co, A) and (A, co) where A is a critical number. Find A = Consider the function f(x) = 5x + 5x-1. For this function there are four important intervals: ( - 00, A], [A, B), (B, C], and [C, oo) where A, and C are the critical numbers and the function is undefined at B. Determine A, B, and C. Consider the function f(x) = rvr + 4, defined on the interval -4
