WebIn order for 𝑓(𝑥) to be concave up, in some interval, 𝑓 ''(𝑥) has to be greater than or equal to 0 (i.e. non-negative) for all 𝑥 in that interval. The same goes for 𝑓(𝑥) concave down, but then 𝑓 ''(𝑥) is non-positive. One use in math is that if f"(x) = 0 and f"'(x)≠0, then you do have an inflection … 1) that the concavity changes and 2) that the function is defined at the point. You … can you get a degree in singingWebDetermine for which x-values the local maxima and minima are reached. 3. Give the intervals of concavity and give the inflection points. 4. Complete the diagram, indicating where the graph of f is concave up/down increasing/decreasing and sketch the graph of the function. 5.
