Pupils solve quadratic equations using graphing. In this algebra instructional activity, students apply the correct form of functions notations. They solve parabolas by graphing and by algebraic expressions and equations.
Here is an unexpected resource: chapter 1 of an Algebra textbook. You can use all or some of its contents to teach your Middle Schoolers all about algebraic expression, domain, function notation, linear equations, order of operations, input/output, ordered pairs, and variable expressions. This would be great for a substitute or newer teacher looking for reliable tools.
Show learners that function notation and multiplication notation are not the same. In the example, Katie is given a function, C(x), which is the cost of producing x amount of DVDs. Ask learners if Katie can divide the function notation, C(x), by x when finding the average.
A simple definition of f(x). Function notation.
Students apply the concept of functions to the real world. For this algebra lesson, students define inverse function and practice using the correct function notations. They graph and define functions as relations.
Learners solve problems and answer questions on Gateway. In this algebra lesson, students evaluate and solve problems using the correct function notation. They represent function in the real world.
Students investigate reflections and symmetry about a line. For this algebra lesson, students apply function notations correctly to solve problems. They differentiate between even and odd function and discuss the reason for their names.
High schoolers, after completing a warm up exercise on one proportion word problem, distinguish between functions and non-functions. They identify domain and range on a function as well as recognize and implement function notation. They solve problems on the board in groups.
Using a TI-Nspire calculator, learners will work to better understand function notation and input/output functions. They write equations with a function symbols, identify what makes an equation a function, and graph lines in order to classify them as functions or not.
Young scholars differentiate between function and relation by analyzing graphs and data to determine if the pair of coordinates are a function or not. They rewrite functions using the correct notations. This lesson is broken down into timed segments which makes for easy planning.
Students collect and analyze data. In this algebra instructional activity, students evaluate and solve functions using the correct notation. They analyze data using tables and graphs.
The purpose of this exercise is to give practice in reading information about a function from its graph. Learners are given graphs of two functions on the same axes. The task is to locate and label various key points on the graph that are identified using function notation. The activity is appropriate for instruction to help facilitate understanding of functions or as an assessment item. 
The longer you wait to try the new pizza place, the more it's going to cost you! This real-world problem about how the cost of pizza varies with respect to time is a good example of how piecewise functions are used to describe relationships between quantities in everyday life. Learners use the given function to answer questions about the price of a pizza in six different scenarios. The exercise is suitable for either instruction or assessment.  
Learners investigate trigonometric function.  In this Algebra II instructional activity, students explore functional notation and transformational graphing of trigonometric functions. 
Every topic or subject has its own special jargon. Learners work on their math vocabulary as it relates to basic algebra terms. They define and identify function, functional notation, ordered pairs, rate of change, slope, and y-intercept. Then using tables and graphs they use the slope and y-intercept to graph the posed function.  
In this graphing worksheet, one completes 13 problem solving questions regarding quadratic functions and function notation. The emphasis is on understanding parent functions and transformations. 
Here is a complete chapter on graphing linear equations and functions. Learners review graphing points on a coordinate plane, graph lines and functions, and write linear equations.
Students rewrite word problems using algebraic symbols. In this algebra activity, students explore piecewise functions through graphing and identifying the reasons for open and closed dots or solid and dotted lines. They derive the formula given the graph of a piecewise.
Students define and complete reflection of functions. In this algebra lesson, students identify the type of symmetry that exist and the type of reflection being done.
Young scholars differentiate polynomial graphs based on their vertical and horizontal shifts. In this algebra lesson plan, students explain what happens during a vertical and horizontal shift. They examine their equation written in vertex form to help them decipher the shift of their graph.
