Chapter 3
1) A quadratic function is an equation of the form f(x) = ax^2 + bx + c, where a ≠ 0. Its graph is a parabola.
2) The vertex of a parabola is the point where it intersects its axis of symmetry. If a > 0, the parabola opens upward and the vertex is a minimum. If a < 0, it opens downward and the vertex is a maximum.
3) The standard form of a quadratic equation is f(x) = a(x - h)^2 + k, where the vertex is (h, k) and the axis of symmetry is x = h.

The document defines square roots and provides examples of finding square roots of perfect squares. It explains that the square root of a number is the value that, when multiplied by itself, equals the original number. For example, the square root of 16 is 4 because 4 x 4 = 16. It also notes that a number can have two square roots, such as the square roots of 25 being 5 and -5. Examples are provided of evaluating square root expressions of perfect squares.
Responsive images
The document discusses responsive images and how to efficiently load properly sized images that fit the page design. It notes that images account for over half the average page size and bandwidth is expensive on mobile. The key techniques discussed are using srcset and sizes attributes to load the best sized image based on screen width, and using x descriptors and art direction with <picture> for high DPI screens. Implementing responsive images can reduce image file sizes by over 70%.

Raphael wants to make enlarged posters of his advertisement to display at a sale. He has an 8.5" by 11" ad and wants to enlarge it as much as possible using the copy machines at his local copy shop, which can enlarge documents between 50-200% and have paper sizes of 8.5" by 11", 11" by 14", and 11" by 17". The best option would be to use the 11" by 17" paper and enlarge the ad 150% to make it a similar, larger poster without trimming off the edges of the paper.

Social Connections and Wellbeing in Later Life
The study examined the relationship between caregiving transitions and emotional well-being among older adults using data from the English Longitudinal Study of Ageing (ELSA). It found that among older women, long-term caregiving was associated with decreased quality of life and increased depressive symptoms over time. Cessation of caregiving duties was also linked to poorer emotional well-being. The findings suggest caregiving takes an emotional toll and highlight the need for support during different stages of a caregiving career.

Intercepts
This document explains how to find the x-intercept and y-intercept of a graph from its equation. The x-intercept is where the graph crosses the x-axis and is of the form (x,0), while the y-intercept is where the graph crosses the y-axis and is of the form (0,y). To find the x-intercept, set y=0 and solve for x; to find the y-intercept, set x=0 and solve for y. Examples are provided finding the intercepts of equations by setting variables equal to 0 and solving.

Optimal Finite Difference Grids
Optimal Finite-Difference Grids for Elliptic Problem
In many applications one observes rapid change of the solution in the boundary region. Accurate and numerically efficient resolution of the solution close to the moving boundaries is considered to be and important problem. We develop an approach to grid optimization for finite-difference scheme for elliptic problem. Using this approach we are able to achieve exponential convergence of the boundary Neumann-to-Dirichlet map when applied to the bounded domains. It increases the convergence order without increasing the stencil size of the finite-difference scheme and without losing stability.

Lecture 1.2 quadratic functions
The document discusses the differences and relationships between quadratic functions and quadratic equations. It notes that quadratic functions can take any real number as an input, while quadratic equations only have two solutions. The roots of a quadratic equation are also the x-intercepts of the graph of the corresponding quadratic function. The remainder theorem states that the value of a polynomial when a number is substituted for the variable is equal to the remainder when the polynomial is divided by the linear factor corresponding to that number. This connects the roots of quadratic equations to factors of quadratic functions. A quadratic can only have two distinct roots, as having three would mean it has an infinite number of roots.
