It's clear, hopefully, that the second derivative will only be zero at \(t = 0\). Using this we can see that the second derivative will be negative if \(t < 0\) and positive if \(t > 0\). So the parametric curve will be concave down for \(t < 0\) and concave up for \(t > 0\). Here is a sketch of the curve for completeness sake.For a quadratic function f (x) = ax2 +bx + c, if a > 0, then f is concave upward everywhere, if a < 0, then f is concave downward everywhere. Wataru · 6 · Sep 21 2014.The graph is concave down when the second derivative is negative and concave up when the second derivative is positive. Concave down on (−∞,0) ( - ∞, 0) since f ''(x) f ′′ ( x) is …Walkthrough of Part A. To determine whether f (x) f (x) is concave up or down, we need to find the intervals where f'' (x) f ′′(x) is positive (concave up) or negative (concave down). Let’s first find the first derivative and second derivative using the power rule. f' (x)=3x^2-6x+2 f ′(x) =3x2 −6x+2.

f(x) is concave on (-oo,-4.5) and (0,oo), and f(x) is convex on (-4.5,0). To find where a function is concave up, find where the second derivative of the function is positive. f(x)=-x^4-9x^3+2x+4 Find f'(x): f'(x)=-4x^3-27x^2+2 Next, find f''(x): f''(x)=-12x^2-54x f''(x)=(-6x)(2x+9) Set f''(x) equal to zero to find inflection points 0=(-6x)(2x+9) x=0, x=-4.5 After checking the signs of values ...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.

Let's look at the sign of the second derivative to work out where the function is concave up and concave down: For \ (x. For x > −1 4 x > − 1 4, 24x + 6 > 0 24 x + 6 > 0, so the function is concave up. Note: The point where the concavity of the function changes is called a point of inflection. This happens at x = −14 x = − 1 4.

Apr 24, 2022 · The concavity changes at points b and g. At points a and h, the graph is concave up on both sides, so the concavity does not change. At points c and f, the graph is concave down on both sides. At point e, even though the graph looks strange there, the graph is concave down on both sides – the concavity does not change. Let's look at the sign of the second derivative to work out where the function is concave up and concave down: For \ (x. For x > −1 4 x > − 1 4, 24x + 6 > 0 24 x + 6 > 0, so the function is concave up. Note: The point where the concavity of the function changes is called a point of inflection.
