For a function of three variables, a level set is a surface in three-dimensional space that we will call a level surface. For a constant value c c in the range of f(x, y, z) f (x, y, z), the level surface of f f is the implicit surface given by the graph of c = f(x, y, z) c = f (x, y, z).

Oct 2, 2024 · A graph is a set of vertices/nodes that are connected by edges/pointers. Graphs can be placed into the following categories: Directed Graph: The edges can only be traversed in one direction. Undirected Graph: The edges can be traversed in both directions. Weighted Graph: A value is attached to each edge. Computers are able to process graphs by ...
A graph with six vertices and seven edges. In discrete mathematics, particularly in graph theory, a graph is a structure consisting of a set of objects where some pairs of the objects are in some sense "related". The objects are represented by abstractions called vertices (also called nodes or points) and each of the related pairs of vertices ...

In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things. Here, for instance, we can represent the data given below, the type and number of school supplies used by students in a class, on a gra...
Pictograph
The representation of the information through pictures is called pictograph. A certain number of items is represented by each picture. For example, you can use a picture of a cricket bat to display how many cricket bats are sold by a shop during a certain week. In this pictograph, 1 picture of the cricket bat represents 4 cricket bats. So, according to the graph, 12 bats (4 + 4 + 4) were sold on Tuesday.
Bar Graph
A bar graph is the representation of numerical data by rectangles (or bars) of equal width and varying height. The gap between one bar and another is uniform throughout. Bar graphs can be either horizontal or vertical. The height or length of each bar relates directly to its value.
Line Graph:
A line graphuses dots connected by lines to show the changes over a period of time.
Example1: State whether the given statements are true or false. 1. In a bar graph, the width of bars may not be equal. 2. In a bar graph, bars of uniform width can be drawn both vertically as well as horizontally. 3. In the bar graph, the gap between two consecutive bars may not be the same. 4. In the bar graph, each bar represents only one value o...
Key Terms. plot: a graph or diagram drawn by hand or produced by a mechanical or electronic device. A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables. The plot can be drawn by hand or by a mechanical or electronic plotter.
