CALC:
f(-5)=4; f(0)=0; f(5)=-4
f'(-5)=f'(0)=f'(5)=0;
f'(x)>0 if |x|>5; f'(x)<0 if 0<|x|<5

how would you graph that?
so we have points (-5,4), (0,0), and (5, -4)
what would you do about the derivatives? where does it concave up/down and how can you tell?

CALC:
f(-5)=4; f(0)=0; f(5)=-4
f'(-5)=f'(0)=f'(5)=0;
f'(x)>0 if |x|>5; f'(x)<0 if 0<|x|<5

------

1. plot the points given on the graph (duh)
2. f'(-5) = 0. this means that at (-5, 4), the slope of the graph is zero.
3. f'(0) = 0. this means that at (0,0), the slope of the graph is zero. same thing with (5,-4)

okay i suck at explaining. i'll draw--er, sketch really badly the graph.


this should be right....i'm not so great with MS paint. i can explain stuff more if you need me to.

yeah so near the right ish, it looks like the slope is zero for a range of values, but its not supposed to be like that. haha sorry, it was the best i could do. also i didn't really draw that the graph had a slope of 0 at (0,0) but it should be.
