What is an integral and how do you find the integral of a function?
Answer coming soon!
At what point does the function F(x) = 4x^4 + 5x^3 change from concave up to concave down?
Here we can do what we described in last weeks problem. First, we have to find the second derivative:
F''(x) = 48x^2 + 30x
Now we have to find the critical values:
F''(x) = 6x(8x+5) = 0
x = 0, -5/8
Now we can test points in between the lines to find that the graph changes from positive to negative at -5/8.
At what point does a function change from concave up to concave down?
(This is a conceptual question that doesn’t require calculations)
This question is actually quite simple. While you can attempt to locate a point of inflection visually with a graph, it may not always be accurate. When a function changes from concave up to concave down, the function’s second derivative must intersect zero and change from positive to negative.
