Using the second derivative test, f(x) is concave up when x<-1/2 and concave down when x> -1/2. Concavity has to do with the second derivative of a function. A function is concave up for the intervals where d^2/dx^2f(x)>0. A function is concave down for the intervals where d^2/dx^2f(x)<0. First, let's solve for the second derivative of the function.

Details. To visualize the idea of concavity using the first derivative, consider the tangent line at a point. Recall that the slope of the tangent line is precisely the derivative. As you move along an interval, if the slope of the line is increasing, then is increasing and so the function is concave up. Similarly, if the slope of the line is ...Now that we know the second derivative, we can calculate the points of inflection to determine the intervals for concavity: f ''(x) = 0 = 6 −2x. 2x = 6. x = 3. We only have one inflection point, so we just need to determine if the function is concave up or down on either side of the function: f ''(2) = 6 −2(2)Now, we take the second derivative of the function, set it equal to #0#, and solve for its roots: #(d^2y)/dx^2=30x^4-80x^3# #10x^3(3x-8)=0# #x=0 and 8/3# These are the inflection points. We have to conduct the second derivative test to find whether the function is concave up or down before and after each of these points.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.Answer: Therefore, the intervals where the function f(x)=x^4-8x^3-2 is concave up are (-∈fty ,0) and (4,∈fty ) , and the interval where it is concave down is (0,4).. Explanation: To find the intervals where a function is concave up and concave down, we need to examine the sign of the second derivative. 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.
