Question 1 1 pts The absolute maximum and local maximum of the function f (x) = cos(x) is 1. O True O False Question 2 1 pts Five is a local max of the function f (x) = 3x4 - 16x3 + 18x2. O True O False Question 3 1 pts The function f (a) = as has neither an absolute max nor an absolute min. O Tru O False Question 4 1 pts If the function f is continuous on an open interval (a , b) , then f must attain an absolute value f (c) at some number cin (a, b) True False Question 5 1 pts If f' (c) = 0, then f (c) is a local max or local min. O True False Question 6 1 pts The definition of a critical number is: A critical number of a function f is a number in the domain of the function f such that f' (c) = 0. O True O False Question 7 1 pts The critical numbers of the function f (x) = 23 - 3x2 + 1, ->
