Determine the interval(s) of the domain over which f has positive concavity (or the graph is "concave up"). (2, 4) (3, 5): invalid interval notation b. Determine the interval(s) of the domain over which f has negative concavity (or the graph is "concave down").An inflection point occurs at a point where the function changes its concavity from concave up to concave down or concave down to concave up. At inflection points, f′ f ′ has extrema. Thus, when given a graph of a function f f, if on the interval I I the graph is bent upward, so the slope of f f is increasing, it is concave up, if the graph ...
First, recall that the area of a trapezoid with a height of h and bases of length b1 and b2 is given by Area = 1 2h(b1 + b2).

Sample Size CalculationNow you make a test interval from: #(-oo,0)uu(0,3)uu(3,oo)# You test values from the left and right into the second derivative but not the exact values of #x#. If you get a negative number then it means that at that interval the function is concave down and if it's positive its concave up. If done so correctly you should get that:
To check that f f is concave, for every point x ∈ (a, b) x ∈ ( a, b) you need to construct the tangent of f f at that point and check that the graph of f f is never below the tangent (but may be equal to it) at any points in (a, b) ( a, b). To check that f f is concave, you calculate f′ f ′, and check that it is always increasing, which ...
