Then, set the partial derivatives equal to zero and solve the system of equations to find the critical points. Use the second partial derivative test in order to classify these points as maxima, minima or saddle points. When the second derivative is negative, the function is concave downward. And the inflection point is where it goes from concave upward to concave downward (or vice versa). Example: y = 5x 3 + 2x 2 − 3x. Let's work out the second derivative: The derivative is y' = 15x2 + 4x − 3. The second derivative is y'' = 30x + 4.

First, I would find the vertexes. Then, the inflection point. The vertexes indicate where the slope of your function change, while the inflection points determine when a function changes from concave to convex (and vice-versa). In order to find the vertexes (also named "points of maximum and minimum"), we must equal the first derivative of the function to zero, while to find the inflection ...Concavity of graphs of functions - Concave up and down.
