a)If this figure is the graph of the second derivative f"(x), where do the points of inflection of occur, and on which interval is concave down?
b) If this is the graph of the derivative , where do the points of inflection of occur, and on which interval is concave down? I know the answer to this one is b,e ;(b,e)
Basically how do I tell?
So if I look at just f(x), the inflection points are the min and max.(?) And concave downwards is just like a downwards parabola
If I look at f'(x), are the inflection points still the min and max? And concave downwards is a negative slope? I'm confused on this part...
And for f''(x)...don't even get me started
Seriously, if anyone can fill in any of this questions...you'd be my favorite person ever!
