  • Functions a level maths. PDF A function is like a machine that takes an input and gives an output. We break down the definition of the function given in set-builder form and plot the graph by connecting points on the cartesian plane. There's another powerful thing we can do with functions - we can use them to take in some values, compute them, and return a new value. Functions are used in all sorts of real-world applications! For example, we use functions to model physical processes, like the motion of a car or the growth of a population. We'll evaluate, graph, analyze, and create various types of functions. This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing linear equations/functions - Interpreting linear equations/functions - Linear equations/functions word problems What are rational functions? How do we plot them? What is their domain and range? Let's find out. Think about all the things you can do with a calculator - add values, subtract, calculate square root, multiply, etc. In this video, we see examples of various kinds of functions. This simple-yet-rich idea opens up a world of fascinating applications. Let's explore how we can graph, analyze, and create different types of functions. Functions assign a single output for each of their inputs. Unit guides are here! Power up your classroom with engaging strategies, tools, and activities from Khan Academy’s learning experts. Watch Jesse Roe and Sal talk about the difference between equations and functions. We can compose functions by making the output of one function the input of another one. Tables, equations, and graphs of functions Learn Does a vertical line represent a function? What are rational functions? How do we plot them? What is their domain and range? Let's find out. In this unit, we learn about functions, which are mathematical entities that assign unique outputs to given inputs. Functions assign a single output for each of their inputs. PDF This topic covers: - Evaluating functions - Domain & range of functions - Graphical features of functions - Average rate of change of functions - Function combination and composition - Function transformations (shift, reflect, stretch) - Piecewise functions - Inverse functions - Two-variable functions A function is like a machine that takes an input and gives an output. Domain and Range is calculated through visually observing the graph. Equations and functions are not the same thing, but they can be related in several ways. Inverse functions undo each other when we compose them.
