Local extrema are the highest or lowest points within a specific interval or neighborhood of a function, while global extrema are the highest or lowest points of the entire function. In other words, local extrema are relative to a specific region of the function, while global extrema are absolute and apply to the entire function. Local extrema can occur at points where the derivative of the function is zero or undefined, while global extrema occur at the endpoints of the interval or at critical points within the interval.

### Are all global extrema also local extrema of polynomial functions?

No, not all global extrema are also local extrema of polynomial functions. A global extremum is a point where the function has the highest or lowest value over its entire domain, while a local extremum is a point where the function has the highest or lowest value in a specific neighborhood. A polynomial function can have global extrema that are not local extrema if the function continues to increase or decrease beyond the neighborhood of the extremum.

Extrema of a function can be determined by finding the critical points where the derivative is equal to zero or undefined. These critical points are then evaluated to determine if they correspond to a maximum or minimum value. Additionally, the endpoints of the interval being considered should also be checked to see if they are extrema. By analyzing the critical points and endpoints, one can determine the extrema of a function.

Local extrema are points on a graph where a function reaches a maximum or minimum value within a specific interval. A local maximum is the highest point in a small neighborhood of a function, while a local minimum is the lowest point in that neighborhood. These points are called "local" because they may not be the absolute highest or lowest points of the entire function, but rather within a limited range.

Extrema are determined by finding the critical points of a function, which are points where the derivative is either zero or undefined. To find these critical points, we set the derivative of the function equal to zero and solve for the variable. We then evaluate the function at these critical points as well as at the endpoints of the interval of interest to determine the maximum and minimum values. The highest value among these points is the maximum (if it exists), and the lowest value is the minimum (if it exists).

### When do global extrema occur?

Global extrema occur at the highest or lowest points of a function over its entire domain. For a function to have a global maximum, the value of the function at that point must be greater than or equal to the value of the function at all other points in its domain. Similarly, for a function to have a global minimum, the value of the function at that point must be less than or equal to the value of the function at all other points in its domain.

Boundary extrema are not always present in all situations. In some cases, there may be a continuous range of values without distinct boundaries, making it difficult to identify extrema. Additionally, in certain scenarios, the extrema may be located at interior points rather than at the boundaries. Therefore, the presence of boundary extrema depends on the specific context and nature of the problem being considered.

Local extrema are points on a function where the function reaches a maximum or minimum value within a small neighborhood of that point. Global extrema, on the other hand, are points where the function reaches the maximum or minimum value over the entire domain of the function. Local extrema can occur at points where the derivative of the function is zero, while global extrema can occur at endpoints of the domain or at points where the derivative is zero.

No, local extrema cannot be infinite. Local extrema refer to the maximum or minimum values of a function within a specific interval, and these values are finite. Infinite values would not qualify as local extrema because they do not represent a maximum or minimum within a specific range.

Extrema under constraints refer to the maximum or minimum values of a function subject to certain conditions or restrictions. These constraints can be in the form of equations or inequalities that limit the possible values of the variables. Finding extrema under constraints involves optimizing the function while satisfying these restrictions, which often requires the use of techniques such as Lagrange multipliers or substitution methods. The solutions obtained in this way represent the highest or lowest values that the function can achieve within the given constraints.

Local extrema are the highest or lowest points within a specific interval or region of a function. They can be either a local maximum (the highest point in the interval) or a local minimum (the lowest point in the interval). Global extrema, on the other hand, are the absolute highest or lowest points of the entire function, not just within a specific interval. These points represent the overall maximum or minimum values of the function.

To find local extrema in mathematics, you need to first find the critical points of the function by taking the derivative and setting it equal to zero. Then, you can use the second derivative test to determine whether each critical point is a local maximum, local minimum, or neither. If the second derivative is positive at a critical point, it is a local minimum, and if it is negative, it is a local maximum.
