Points of Inflection are locations on a graph where its concavity changes from concave up to concave down, or vice versa.
Imagine you are riding a roller coaster. Points of Inflection are like the moments when the roller coaster changes from going up to going down, or from going down to going up.
Concavity: This refers to whether a graph is opening upwards like a "U" shape (concave up) or downwards like an "n" shape (concave down).
Second Derivative Test: The Second Derivative Test helps determine if critical points correspond to local maxima, local minima, or neither.
Higher Order Derivatives: These are derivatives obtained by differentiating multiple times. For example, the second derivative is obtained by differentiating twice.
