Find concave up and down calculator.

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.

concavity. Concavity describes the behavior of the slope of the tangent line of a function such that concavity is positive if the slope is increasing, negative if the slope is decreasing, and zero if the slope is constant. decreasing function. A decreasing function is one with a graph that goes down from left to right.If f '' > 0 on an interval, then f is concave up on that interval. If f '' 0 on an interval, then f is concave down on that interval. If f '' changes sign (from positive to negative, or from negative to positive) at some point x = c, then there is an Inflection Point located at x = c on the graph. The above image shows an Inflection Point.

The second derivative is negative when x<1, positive when x>1, and zero when x=1 (and of course changes sign as x increases "through" x=1). That means the graph of f is concave down when x<1, concave up when x>1, and has an inflection point at x=1.

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.

Intervals where f(x) is concave up: −12x − 6 > 0. −12x > 6. ⇒ x < −1/2. Intervals where f(x) is concave down: −12x − 6 < 0. −12x < 6. ⇒ x > −1/2

We must first find the roots, the inflection points: f′′ (x)=0=20x3−12x2⇒ 5x3−3x2=0⇒ x2 (5x−3)=0. The roots and thus the inflection points are x=0 and x=35. For any value greater than 35, the value of 0">f′′ (x)>0 and thus the graph is convex. For all other values besides the inflection points f′′ (x)<0 and thus the graph ...
