I don't understand entirely how to do them, and I have a test coming soon, so I could really use your help. Thanks. Concavity and the Second Derivative Test 2.$\ \ \$Suppose you are given a formula for a function $f$. a)$\ \ \$How do you determine where $f$ is increasing or decreasing? b)$\ \ \$How do you determine where the graph of $f$ is concave upward or downward? c)$\ \ \$How do you locate inflection points? 4.$\ \ \$If $f(x) = \frac{x^2}{x^2 - 1}$, find (a) the intervals on which $f$ is increasing or decreasing, (b) the $x$-values of local maximum and minimum values, and (c) the intervals of concavity and inflection points. Justify each response. 6.$\ \ \$If $f(x) = x + \frac4x$, find all relative extrema using the second derivative test. Justify your response. Last edited by skipjack; February 21st, 2019 at 06:31 AM.
