Concave downward graph.

Step 1. In Exercises 5 through 20, determine where the given function is increasing and decreasing and where its graph is concave upward and concave downward. Sketch the graph of the function. Show as many key features as possible (high and low points, points of inflection, vertical and horizontal asymptotes, intercepts, cusps, vertical tangents).The graph of a function \(f\) is concave down when \(\fp \)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 3.4.3, where a concave down graph is shown along with some tangent lines. Notice how the tangent line on the left is steep, upward ... Anyway here is how to find concavity without calculus. Step 1: Given f (x), find f (a), f (b), f (c), for x= a, b and c, where a < c < b. Where a and b are the points of interest. C is just any convenient point in between them. Step 2: Find the equation of the line that connects the points found for a and b. Similarly, f is concave down (or downwards) where the derivative f ′ is decreasing (or equivalently, f ″ is negative). Graphically, a graph that's concave up has a cup shape, ∪ , and a graph that's concave down has a cap shape, ∩ . An inflection point only requires: 1) that the concavity changes and. 2) that the function is defined at the point. You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f"(x) = 0 OR if f"(x) is undefined. An example of the latter situation is f(x) = x^(1/3) at x=0.

We know that the sign of the derivative tells us whether a function is increasing or decreasing; for example, when f′ (x)>0, f (x) is increasing.The graph of y=f (x) is concave down when the derivative f’ (x) is decreasing or equivalently when the second derivative f” (x)<0. In this case f (x)=- (5/x)-2 so f’ (x)=5/x^2 and f” (x)=-10/x^3 and hence f” (x)<0 if and only if x<0. Answer: x < 0. Still looking for help?
