A function $f(x)$ is defined for $x$ -values between 0 and 8. The graph below shows a graph of the derivative of $f(x)$ .

1. Point A corresponds to a

local minimum of $f(x)$ local maximum of $f(x)$ neither a local max nor a min of $f(x)$ you can’t tell without more information

2. Point B corresponds to a

local minimum of $f(x)$ local maximum of $f(x)$ neither a local max nor a min of $f(x)$ you can’t tell without more information

3. Point C corresponds to a

local minimum of $f(x)$ local maximum of $f(x)$ neither a local max nor a min of $f(x)$ you can’t tell without more information

4. Point D corresponds to a
