Derivative of concave up
WebLet's see if we can use the derivatives to tell us that it is concave up: The first derivative is 2 x, which is always increasing. So the first derivative tells us the graph is concave up. The second derivative is 2, which is positive! So the second derivative test tells us that the graph is concave up. Both tests give us the correct answer! WebA mnemonic for remembering what concave up/down means is: “Concave up is like a cup; concave down is like a frown.” It is admittedly terrible, but it works. Our definition of concave up and concave down is given in terms of when the first derivative is …

Webconcave: [adjective] hollowed or rounded inward like the inside of a bowl. WebJan 3, 2024 · 1. 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.

WebJul 12, 2024 · Likewise, when a curve opens down, such as the parabola or the opposite of the exponential function , we say that the function is concave down. This behavior is linked to both the first and second derivatives of the function. In Figure 1.31, we see two functions along with a sequence of tangent lines to each.
