Functions and Their Graphs: Unit 2 Functions And Their Graphs Homework 1
Functions are mathematical relationships that assign a unique output value to each input value within a specific domain. Their graphs provide visual representations of these relationships, allowing us to analyze and understand the behavior of functions.
Different types of functions, such as linear, quadratic, and exponential, exhibit distinct graph shapes. Linear functions form straight lines, quadratic functions create parabolas, and exponential functions produce curves that increase or decrease rapidly.
To graph functions, we can use tables of values and plot the corresponding points. By connecting these points, we obtain the function’s graph, which provides insights into its characteristics, such as intercepts, extrema, and domain and range.
