Minimization
In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in terms of global or local range. The definition of minimization in the thesaurus is the process of reducing something to a small amount, value, or position. Minimization (noun) is an instance of belittling or disparagement.
Maxima and Minima
The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.
Derivatives
A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which one would be easier? Walking on the road would be much easier than climbing a mountain.
Concavity
In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the first derivative test and second derivative test to understand the concave behavior of the function.
![### Reflection of a Triangle across the y-Axis
**Look at Triangle JKL.**
[Graph Description]
In the provided graph, we can see a coordinate plane with both the x-axis and y-axis labeled. The graph contains a triangle labeled \(JKL\), with its vertices as follows:
- \(J\) at (-5, 3)
- \(K\) at (-4, 1)
- \(L\) at (-2, 5)
The triangle is positioned in the second quadrant of the coordinate plane.
**Reflection Process**
After a reflection over the y-axis, each point of Triangle \(JKL\) moves directly across the y-axis to an equal distance on the opposite side. Each x-coordinate of the vertices will change signs, while the y-coordinates will remain the same.
**Problem Statement**
"After a reflection over the y-axis, the image of Triangle JKL is Triangle J'K'L'. What are the coordinates of the point K'?"
Transformation for reflection over the y-axis is given by:
\[ (x, y) \rightarrow (-x, y) \]
Given \(K\) at (-4, 1), the reflected point \(K'\)'s coordinates will be:
\[ K' = (4, 1) \]
Therefore, the coordinates of the point \(K'\) are:
\[ (4, 1) \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2d6de9b6-a0c8-4f97-b6c2-3ab2e7c175de%2Ffc0913eb-4561-4e14-8a33-27abe60fc5b0%2Fzgbws8r_processed.jpeg&w=3840&q=75)
