Determine concavity from graph
WebDec 5, 2016 · 1. Here x = 0 is the critical value since f ′ ′ ( 0) is undefined. Now use this to divide out your intervals into two intervals. ( − ∞, 0) and ( 0, ∞). Pick a test point on each interval and see whether the f ′ ′ ( t e s t v a l … WebShort answer: no. Since the function f is not defined by some formula, only by the graph sal draw, you cant say wether or not these are parabolas. That being said, let's assume f (x) = x^3 since the graph look very similar to a …

Weby ″ = 24 x + 6. Let's look at the sign of the second derivative to work out where the function is concave up and concave down: For \ (x. For x > − 1 4, 24 x + 6 > 0, so the function is concave up. Note: The point where the concavity of the function changes is called a point of inflection. This happens at x = − 1 4.
