WebIf the graph curves, does it curve upward or curve downward? This notion is called the concavity of the function. Figure 5 (a) shows a function f with a graph that curves upward. As x increases, the slope of the tangent line increases. Thus, since the derivative increases as x increases, f is an increasing function. WebThe graph of f (blue) and f '' (red) are shown below. It can easily be seen that whenever f '' is negative (its graph is below the x-axis), the graph of f is concave down and whenever …

Conic Sections: Ellipse with Foci WebWe see this phenomenon graphically as the curve of the graph being concave up, that is, shaped like a parabola open upward. Likewise, if the second derivative is negative, then the first derivative is decreasing, so that the slope of the tangent line to the function is decreasing asxincreases. danby compact washing machine
