Question
Use the graph of $y=f(x)$ to identify(A) The local extrema of $f(x)$.(B) The inflection points of $f(x)$.(C) The numbers $u$ for which $f^{\prime}(u)$ is a local extremum of $f^{\prime}(x)$
Step 1
From the graph, we can see that $f'(x)$ is zero at $x=-2$ and $x=2$. Therefore, the local extrema of $f(x)$ are at $x=-2$ and $x=2$. Show more…

Graphing and Optimization
Second Derivative and Graphs
Use the derivative of the function $y=f(x)$ to find the points at which $f$ has a (a) local maximum, (b) local minimum, or (c) point of inflection. $$y^{\prime}=(x-1)^{2}(x-2)$$
Applications of Derivatives
Connecting f and f with the Graph of f
Use the derivative of the function $y=f(x)$ to find the points at which $f$ has a (a) local maximum, (b) local minimum, or (c) point of inflection. $$y^{\prime}=(x-1)^{2}(x-2)(x-4)$$
