# What is the second derivative on a graph?

The second derivative of a function f measures the concavity of the graph of f. A function whose second derivative is positive will be concave up (also referred to as convex), meaning that the tangent line will lie below the graph of the function.

Moreover, what does 2nd derivative tell you?

The second derivative tells us a lot about the qualitative behaviour of the graph. If the second derivative is positive at a point, the graph is concave up. If the second derivative is positive at a critical point, then the critical point is a local minimum. The second derivative will be zero at an inflection point.

Also Know, is second derivative acceleration? The second derivative is the rate of change of the rate of change of a point at a graph (the "slope of the slope" if you will). This can be used to find the acceleration of an object (velocity is given by first derivative).

Just so, how do you find the inflection point on a second derivative graph?

An inflection point is a point on the graph of a function at which the concavity changes. Points of inflection can occur where the second derivative is zero. In other words, solve f '' = 0 to find the potential inflection points. Even if f ''(c) = 0, you can't conclude that there is an inflection at x = c.

What does 2nd derivative tell us?

The second derivative of a function f measures the concavity of the graph of f. A function whose second derivative is positive will be concave up (also referred to as convex), meaning that the tangent line will lie below the graph of the function.
