Function f is graphed. The x-axis goes from negative 4 to 4. The graph consists of a curve. The curve starts in quadrant 3, moves upward with decreasing steepness to about (negative 1.3, 1), moves downward with increasing steepness to about (negative 1, 0.7), continues downward with decreasing steepness to the origin, moves upward with increasing steepness, and ends in quadrant 1.Concavity relates to the rate of change of a function's derivative. A function f is concave up (or upwards) where the derivative f ′ is increasing. This is equivalent to the derivative of f ′ , which is f ″ , being positive. Similarly, f is concave down (or downwards) where the derivative f ′ is decreasing (or equivalently, f ″ is ...(Enter your answers as comma-separated lists.) locations of local minima x = locations of local maxima x = (c) Determine intervals where f is concave up or concave down.

The concavity of a function/graph is an important property pertaining to the second derivative of the function. In particular: If 0">f′′(x)>0, the graph is concave up (or convex) at that value of x.. 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 ...Free functions and line calculator - analyze and graph line equations and functions step-by-step When the second derivative is negative, the function is concave downward. And the inflection point is where it goes from concave upward to concave downward (or vice versa). Example: y = 5x 3 + 2x 2 − 3x. Let's work out the second derivative: The derivative is y' = 15x2 + 4x − 3. The second derivative is y'' = 30x + 4. 3. If the second derivative f'' is positive (+) , then the function f is concave up () . 4. If the second derivative f'' is negative (-) , then the function f is concave down () . 5. The point x=a determines a relative maximum for function f if f is continuous at x=a, and the first derivative f' is positive (+) for x<a and negative (-) for x>a.When a function is concave up, the second derivative will be positive and when it is concave down the second derivative will be negative. Inflection points are where a graph switches concavity from up to down or from down to up. Inflection points can only occur if the second derivative is equal to zero at that point. About Andymath.comVideo Transcript. Consider the parametric curve 𝑥 is equal to one plus the sec of 𝜃 and 𝑦 is equal to one plus the tan of 𝜃. Determine whether this curve is concave up, down, or neither at 𝜃 is equal to 𝜋 by six. The question gives us a curve defined by a pair of parametric equations 𝑥 is some function of 𝜃 and 𝑦 is ... Concavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down. We find it convenient to pick a standard terminology and run with it - and in this case concave up and concave down were chosen to describe the direction of the concavity/convexity.
