Function concave up and down calculator.

Thus f is concave up from negative infinity to the inflection point at (1, -1), and then concave down from there to infinity. As always, you should check your result on your graphing calculator. Hint: To get a good feel for the look of this function, you need a fairly odd graphing window — try something like xmin = -2, xmax = 4, ymin = -20, ymax = 20.Question: Given f (x) = (x - 2)^2 (x - 4)^2, determine a. interval where f (x) is increasing or decreasing, b local minima and maxima of f (x) c intervals where f (x) is concave up and concave down, and d. the inflection points of f (x), Sketch the curve, and then use a calculator to compare your answer.

That means as one looks at a concave up graph from left to right, the slopes of the tangent lines will be increasing. Consider Figure 3.4.1 (a), where a concave up graph is shown along with some tangent lines. Notice how the tangent line on the left is steep, downward, corresponding to a small value of f ′.Consequently, to determine the intervals where a function \(f\) is concave up and concave down, we look for those values of \(x\) where \(f''(x)=0\) or \(f''(x)\) is undefined. When we have determined these points, we divide the domain of \(f\) into smaller intervals and determine the sign of \(f''\) over each of these smaller intervals. If \(f ...

The intervals where a function is concave up or down is found by taking second derivative of the function. Use the power rule which states: Now, set equal to to find the point(s) of infleciton.

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.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.
