On the interval (0,6) f' > 0 the function is Increasing. On the interval (6,infinity) f' < 0 and the function is Decreasing. f" = 2x -4 (x-9) and so f" = 0 at x=9; that's the Inflection Point. f" is negative when x < 9 (DOWNWARD concavity) and positive when x > 9 (UPWARD concavity). Thank you!

Corollary 3 of the Mean Value Theorem showed that if the derivative of a function is positive over an interval I then the function is increasing over I. On the other hand, if the derivative of the function is negative over an interval I, then the function is decreasing over I as shown in the following figure. Figure 1.Theorem 3.4.1Test for Concavity. Let f be twice differentiable on an interval I. The graph of f is concave up if f ′′ > 0 on I, and is concave down if f ′′ < 0 on I. If knowing where a graph is concave up/down is important, it makes sense that the places where the graph changes from one to the other is also important.If f′′(x)<0, the graph is concave down (or just concave) at that value of x. If f′′(x)=0 and the concavity of the graph changes (from up to down or vice versa), then the graph is at an inflection point .

Subject classifications. A function f (x) is said to be concave on an interval [a,b] if, for any points x_1 and x_2 in [a,b], the function -f (x) is convex on that interval (Gradshteyn and Ryzhik 2000). 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 f'' is positive (its graph is above the x-axis) the graph of f is concave up. Point (0,0) is a point of inflection where the concavity changes from up to down as x increases (from left to right) and point (1,0) is ... The second derivative tells us if a function is concave up or concave down. If f'' (x) is positive on an interval, the graph of y=f (x) is concave up on that interval. We can say that f is increasing (or decreasing) at an increasing rate. If f'' (x) is negative on an interval, the graph of y=f (x) is concave down on that interval.For each problem, find the x-coordinates of all points of inflection, find all discontinuities, and find the open intervals where the function is concave up and concave down. 1) y = x3 − 3x2 + 4 x y −8 −6 −4 −2 2 4 6 8 −8 −6 −4 −2 2 4 6 8 Inflection point at: x = 1 No discontinuities exist.

The graph of a function f is concave down when f ′ is decreasing. That means as one looks at a concave down graph from left to right, the slopes of the tangent lines will be decreasing. Consider Figure 3.4.1 (b), where a concave down graph is shown along with some tangent lines. Increasing, concave. Correct answer: Decreasing, convex. Explanation: First, let's find out if the graph is increasing or decreasing. For that, we need the first derivative. To find the first derivative, we can use the power rule.
