Find concave up and down calculator.
f (x) = x³ is increasing on (-∞,∞). A function f (x) increases on an interval I if f (b) ≥ f (a) for all b > a, where a,b in I. If f (b) > f (a) for all b>a, the function is said to be strictly increasing. x³ is not strictly increasing, but it does meet the criteria for an increasing function throughout it's domain = ℝ.

(b) Consider b < 0. (i) Find the x-intercepts.(ii) Find the intervals on which f is increasing and decreasing.If the second derivative is positive on a given interval, then the function will be concave up on the same interval. Likewise, if the second derivative is negative on a given interval, the function will be concave down on said interval. So, calculate the first derivative first - use the power rule. #d/dx(f(x)) = d/dx(2x^3 - 3x^2 - 36x-7)#The graph looks concave down to the left and up on the right. Just to be sure, lets do the math. We need to take the first derivative, and that will be easier once we multiply the x through. f(x)=x^3 + x f'(x) = 3x^2 + 1 x^2 = -1/3 Since x^2 would need to be negative, there are no real zeros. This means the min an max will be the endpoints, x ...

Key Concepts. Concavity describes the shape of the curve. If the average rates are increasing on an interval then the function is concave up and if the average rates are decreasing on an interval then the function is concave down on the interval. A function has an inflection point when it switches from concave down to concave up or visa versa.
Before continuing, let's make a few observations about the trapezoidal rule. First of all, it is useful to note that. [Math Processing Error] T n = 1 2 ( L n + R n) where L n = ∑ i = 1 n f ( x i − 1) Δ x and R n = ∑ i = 1 n f ( x i) Δ x. That is, [Math Processing Error] L n and [Math Processing Error] R n approximate the integral ...
Now, plug the three critical numbers into the second derivative: At -2, the second derivative is negative (-240). This tells you that f is concave down where x equals -2, and therefore that there's a local max at -2. The second derivative is positive (240) where x is 2, so f is concave up and thus there's a local min at x = 2.Sometimes you just need a little extra help doing the math. If you are stuck when it comes to calculating the tip, finding the solution to a college math problem, or figuring out h...Note that at stationary points of the expression, the curve is neither concave up nor concave down.
