Question 4 Question 5 1 pts Evaluate sin 1(-1) Suppose y = ect where c * 0 (i.e., c may be positive or negative). If a is a given positive real number, when does y = a? O - O 3nt/2 O When t = [In(a)]/c O When t = [In(a)]/[In(c)] O When t = - [In(a)]/[In(c)] O -3It/2 When t = - [In(a)]/c Question 7 Question 8 1 pts What is the horizontal asymptote of f (a) = 4* - 1? Given the function y = e" where c is any nonzero real number, we compute the doubling time by taking _ -_ and solving for t. Oy =0 Oy = 1 Oy = 1 Oy = 2 Oy = - 1 O y = 1/2 No answer text provided. Question 9 Which is equal to log x y? O 4 (log x + log y) ( 4 log x + log y O (4 log x)(log y) Question 10 What is the value of (f 1)'(8) where f(4) = 8 and f'(4) = 1/2? Enter the exact value
