Tutorial Exercise Determine where the function is concave upward and where it is concave downward. (Enter your answer using interval notation. If an answer does not exist, enter DNE.) f(x) = 3x4 - 36x3 + x – 4 Part 1 of 6 We use the ---Select--- Notice that the domain of f is (Enter your answer using interval notation.) First, find the first and second derivatives of f(x) = 3x – 36x3 + x – 4. f'(x) = f"(x) = Submit Skip (you cannot come back)

Activity 2: Let us try to find where a function is increasing or decreasing given the following.

Activity 2 Show that each function is continuous at the point indicated. 1. f(x) = 3x? – 4x + 2 at x = 2 2. f(x) = 2x? + 4x - 1 at x = -1 3. f(x) = x2 - 6x + 3 at x = 3
