Here are some questions you’ll be asked after you finish watching the videos. Please read through these before watching the videos.

The graph of the function f is shown below.

For these questions, refer to the graph above.

(a) On the interval $[-6, -4]$ , is $f'(x)$ : $<0$ $=0$ $>0$ , or more than one of the above	(b)On the interval $[-4, -2]$ , is $f'(x)$ : $<0$ $=0$ $>0$ , or more than one of the above
(c)On the interval $[0, 2]$ , is $f'(x)$ : $<0$ $=0$ $>0$ , or more than one of the above	(d)On the interval $[2, 4]$ , is $f'(x)$ : $<0$ $=0$ $>0$ , or more than one of the above

For these questions, refer to the graph above.

(a) On the interval $[-6, -4]$ , is $f'(x)$ : increasing decreasing, or more than one of the above	(b)On the interval $[-4, -2]$ , is $f'(x)$ : increasing decreasing, or more than one of the above
(c)On the interval $[0, 2]$ , is $f'(x)$ : increasing decreasing, or more than one of the above	(d)On the interval $[2, 4]$ , is $f'(x)$ : increasing decreasing, or more than one of the above

For how many values of $x$ in the interval $[-8, 10]$ does $f'(x)=0$ ?

From following expressions, identify the smallest and largest according to the numerical value they represent:
