Concave downward graph.

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 x > − 1 4, 24x + 6 > 0 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 = −14 x = − 1 4. Graphically, a function is concave up if its graph is curved with the opening upward (Figure 1a). Similarly, a function is concave down if its graph opens downward (Figure 1b). Figure 1. This figure shows the concavity of a function at several points. Notice that a function can be concave up regardless of whether it is increasing or decreasing.Question: For the graph shown, identify a) the point (s) of inflection and b) the intervals where the function is concave up or concave down. a) The point (s) of inflection is/are (Type an ordered pair. Use a comma to separate answers as needed.) There are 2 …Then "slide" between a and b using a value t (which is from 0 to 1): x = ta + (1−t)b. When t=0 we get x = 0a+1b = b. When t=1 we get x = 1a+0b = a. When t is between 0 and 1 we get values between a and b. Now work out the heights at that x-value: When x = ta + (1−t)b: …

An inflection point 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. Graphically, concave down functions bend downwards like a frown, and concave up function bend upwards like a smile.
