The 2nd derivative is tells you how the slope of the tangent line to the graph is changing. If you're moving from left to right, and the slope of the tangent line is increasing and the so the 2nd derivative is postitive, then the tangent line is rotating counter-clockwise. That makes the graph concave up. chunky cookies near me

WebConcavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down. We find it convenient to pick a standard terminology and run with it - and in this case concave up and concave down were chosen to describe the direction of the concavity/convexity. WebConcave up The upper half breaks down the behavior of f ′ ( x) and f ′ ′ ( x) when the curve is concaving upwards. This shows that the function’s second derivative is positive when the curve is concaving upward. When the …
