Use this calculator to calculate your startup costs so you know how much money you need to start a small business. E)find the local extreme values. For the following exercises, determine a intervals where f is increasing or decreasing, b. Possible Answers: Correct answer: Explanation: The intervals where a function is concave up or down is found by taking second derivative of the function. Use this calculator to calculate properties of a regular polygon. Multiply 5 by 32 and write the answer under 167. (2 different shapes for concave up and down would be preferred. The second derivative of a function f can be used to determine the concavity of the graph of f. 931 ) t , where A ( t ) is measured in pounds and t is measured in days. If f" (10) = - squareroot 2, what do we conclude from the Second Derivative Test? f has a local maximum at x = 10 f has a local minimum at x = 10 f has inflection point at x = 10 f is concave up for x > 10 f is concave down for x 10 f is concave down for x > 10.
