In this article we will cover Construction of a Function Graph, Steps to graph a function, Steps to graph a function. Graphing functions is the process of drawing a curve that represents a function on a coordinate plane. If a function is represented by a
3. A graph is a diagram consisting of points (called vertices) and line segments joining some pairs of points (called edges). Starting with an original graph with five vertices, as shown below, five new graphs are formed by removing one of the vertices from the original graph and all of...
