Functions And Their Graphs
Section 2.1 of the open textbook 'Difference Equations to Differential Equations' by Dan Sloughter, covering the foundational concept of functions and their graphical representations. The section defines functions, domain, range, function notation, composition, and major function classes (polynomials, rational, algebraic, transcendental), with worked examples drawn from physical scenarios. Practical guidance on computer-aided graphing, windowing, and point density is also included.
