Determine increasing/decreasing and concavity

WebThe second derivative of a function may also be used to determine the general shape of its graph on selected intervals. A function is said to be concave upward on an interval if f″(x) > 0 at each point in the interval and concave downward on an interval if f″(x) < 0 at each point in the interval. If a function changes from concave upward to concave downward or vice … WebFree functions Monotone Intervals calculator - find functions monotone intervals step-by-step
