Slide a left and right to see the quadratic of best fit at f(a). ...Recall that the first derivative of the curve C can be calculated by dy dx = dy/dt dx/dt. If we take the second derivative of C, then we can now calculate intervals where C is concave up or concave down. (1) d2y dx2 = d dx(dy dx) = d dt(dy dx) dx dt. Now let's look at some examples of calculating the second derivative of parametric curves.Given the functions shown below, find the open intervals where each function’s curve is concaving upward or downward. a. f ( x) = x x + 1. b. g ( x) = x x 2 − 1. c. h ( x) = 4 x 2 – 1 x. 3.

On what intervals is f concave up? ( ...Concavity and convexity. For the analysis of a function we also need to determine where the function is concave or convex. In other words, we need to determine the curvature of the function. We say that a function f is concave on an interval ( a, b) if for all x ∈ ( a, b) f ″ ( x) < 0 . On the contrary, we say that a function f is convex in ...Graph of y = x^6/30 - x^5/20 - x^4 + 3x + 20, showing intervals of concavity and inflection points. The green vertical lines are not part of the graph, but show where concavity changes. Summary. An inflection point is a point on the graph of a function at which the concavity changes.; Points of inflection can occur where the second derivative is zero.Steps for finding the critical points of a given function f (x): Take derivative of f (x) to get f ' (x) Find x values where f ' (x) = 0 and/or where f ' (x) is undefined.

We can also calculate that [latex]f(0)=0[/latex], giving us a base point for the graph. Using this information, we can conclude the graph must look like this: Figure 4.21interval x < -3 x = -3 -3 < x < 0.1 x ≅ 0.1 0.1 < x < 3 x = 3 3 < x value of f ′ f is concave… interval(s) concave up: interval(s) concave down: points of inflection: Using this information, along with information from Lecture 4.5, we can draw a possible graph for f, which may look something like this: graph of f ′ (x)Plug the left endpoint value x = a1 in for x in the original power series. Then, take the limit as n approaches infinity. If the result is nonzero or undefined, the series diverges at that point. Divergence indicates an exclusive endpoint and convergence indicates an inclusive endpoint. Repeat the process for the right endpoint x = a2 to ...Limit Calculator Determine the intervals on which the following function is concave up or concave down.
