Determine increasing/decreasing and concavity
Did you know?
WebConcavity. We know that the sign of the derivative tells us whether a function is increasing or decreasing at some point. Likewise, the sign of the second derivative f″(x) tells us whether f(x) is increasing or decreasing at x. We summarize the consequences of this seemingly simple idea in the table below: WebFind Where Increasing/Decreasing Using Derivatives f (x)=x^3-75x+3. f (x) = x3 − 75x + 3 f ( x) = x 3 - 75 x + 3.

WebWe now know how to determine where a function is increasing or decreasing. However, there is another issue to consider regarding the shape of the graph of a function. If the graph curves, does it curve upward or curve downward? This notion is called the concavity of the function. Figure 4.34(a) shows a function f f with a graph that curves upward.
