4 days ago · Determine the quadrants: 0 to π/2 — First quadrant, so reference angle = angle; π/2 to π — Second quadrant, so reference angle = π − angle; π to 3π/2 — Third quadrant, so reference angle = angle − π; and; 3π/2 to 2π — Fourth quadrant, so reference angle = 2π − angle.
1 day ago · Given its domain and its codomain, a function is uniquely represented by the set of all pairs (x, f (x)), called the graph of the function, a popular means of illustrating the function. When the domain and the codomain are sets of real numbers, each such pair may be thought of as the Cartesian coordinates of a point in the plane.
23 hours ago · More formally, a graph can be defined as follows: A graph \(G\) consists of a set of \(V\) of vertices (or nodes) and a set \(E\) of edges (or arcs) such that each edge \(e \in E\) is associated with a pair of vertices \(\in V\). A graph \(G\) with vertices \(V\) and edges \(E\) is written as \(G=(V,E)\).
5 days ago · Replace every $\,x\,$ by $\,x-3\,,$ giving the new equation $\,y=(x-3)^2+5\,.$ This moves the graph to the RIGHT $\,3\,$ units. Here are ideas that are needed to understand graphical transformations. Ideas Regarding Functions and the Graph of a Function. A function is a rule: it takes an input, and gives a unique output.

5 days ago · Multiplying the y-values by a number between 0 and 1 moves points closer to the x-axis---the graph gets flatter---and is called a vertical shrink. Horizontal scaling (stretching/shrinking) involves working with the x-values of the points.
4 days ago · In the quadrant \[2\] we have x as negative and y as positive values. In the quadrant \[3\] we have both x and y as negative values. Whereas in the quadrant \[4\] we have x as positive and y as negative value Therefore, in this way quadrants are numbered or ordered in a coordinate plane.
