A relative minimum is a point where the function’s value is less than or equal to the values of the points in a small neighborhood around it. An endpoint is a point where the function is defined but the derivative is undefined. The relationship between relative minimums and endpoints is important in understanding the behavior of functions.
Relative Minimum: Can it be an Endpoint?
A relative minimum is a point on a curve where the function value is smaller than the values at nearby points. In other words, it’s a “low point” on the graph.
An endpoint is a point where the interval of definition of a function ends. For example, if a function is defined on the interval [0, 1], then the endpoints are 0 and 1.
So, can a relative minimum be an endpoint? The answer is yes.
Here are some examples:
- Consider the function f(x) = x^2 on the interval [0, 1]. The relative minimum of this function is at x = 0, which is also an endpoint.
- Consider the function f(x) = |x| on the interval [-1, 1]. The relative minimum of this function is at x = 0, which is also an endpoint.
Here’s why a relative minimum can be an endpoint:
- A relative minimum is a point where the function value is smaller than the values at nearby points.
- An endpoint is a point where the interval of definition of a function ends.
- If the function value at an endpoint is smaller than the values at nearby points, then the endpoint is a relative minimum.
However, it’s important to note that not all relative minimums are endpoints. For example, the function f(x) = x^2 on the interval (0, 1) has a relative minimum at x = 0.5, which is not an endpoint.
Question 1:
Can a relative minimum also be an endpoint of a function?
Answer:
A relative minimum of a function can be an endpoint only if the function is defined at the endpoint and the function value at the endpoint is equal to the relative minimum value. In other words, the graph of the function must touch the endpoint and the function value at the endpoint must be the lowest value in the neighborhood of the endpoint.
Question 2:
What is the difference between a global minimum and a relative minimum of a function?
Answer:
A global minimum of a function is the lowest value of the function over its entire domain, while a relative minimum is the lowest value of the function in a particular neighborhood of a point. A global minimum is always a relative minimum, but a relative minimum may not be a global minimum.
Question 3:
Can a relative maximum of a function also be an endpoint of the function?
Answer:
Yes, a relative maximum of a function can also be an endpoint if the function is defined at the endpoint and the function value at the endpoint is equal to the relative maximum value. This means that the graph of the function must touch the endpoint and the function value at the endpoint must be the highest value in the neighborhood of the endpoint.
