Consider the function at) : Va\": 1. (A) Find f1(1) :0 (B) Use Theorem 7, page 156 of the Stewart Essential Calculus textbook to nd (f'1)'(1) (f'1)'(1) = C] (C) Calculate f_1(:1:) and state domain and range of f'l. Use interval notation. If needed enter inf for 00 or -inf for 00. f'1(m) = Domain = Range = Calculate (f'1)'(1) from the formula for f_1(;c) and check that it agrees with the result of part (B)
