Question 1138898
<br>
(1) f(x) is odd.<br>
That means the graph is symmetric with respect to the origin.
That in turn means that f(0) = 0.<br>
(2) f''(x) is positive for all x > 0.<br>
That means the graph is concave up for all x > 0.
The fact that f(x) is odd then means the graph is concave down for all x < 0.<br>
(3) f'(0) is negative.<br>
That means the slope of the graph at x=0 is negative (downhill to the right).<br>
(4) f'(1) = 0.<br>
That means the slope of the graph is 0 (the tangent to the graph is horizontal) at x=1.
That in turn means the slope is also 0 at x = -1.<br>
(5) f(2) = 0.<br>
That means that f(-2) = 0 also.<br>
I can't draw a graph of such a function, because no kind of graph that I know how to graph with the tools on this forum has all those characteristics.<br>
The graph below of the polynomial {{{y = x^3-4x =(x+2)(x)(x-2)}}} almost works, except that the slopes of 0 are not at exactly x=1 and x=-1.<br>
{{{graph(400,400,-3,3,-10,10,x^3-4x)}}}
