Define, evaluate, and compare functions. Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
A function is a rule which maps a number to another unique number. In other words, if we start off with an input, and we apply the function, we get an output. For example, we might have a function that added 3 to any number. So if we apply this function to the number 2, we get the number 5.
Symbol and Cue Cards. Create a set of symbol cards and matching cue cards as shown on the following pages. Symbol cards: Cards containing math terms, expressions, equations, etc. Cue cards: Cards containing phrases that match one or more of the symbol cards.
To simplify by combining like terms: 1. Search for like terms (same variable raised to the same power; and constants with other constants). 2. Catch the first term and any like terms. 3. Combine them using the addition rules. (SSS, DSD) 4. Continue with other like terms.
Here we will learn about function machines, including finding outputs, finding inputs and using function machines to solve equations. There are also function machine worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
Students are given "input" and "output" numbers and write the rule being used to produce the answer (e.g. "Subtract 6" or "Multiply by 3"). Worksheets cover all 4 operations, and equations are based on standard math facts.
Use what you learned about input-output tables to complete. Exercises 3 and 4 on page 382. Key Vocabulary. input-output table, p. 380. Lesson Tutorials. Input-Output Tables. A function can be represented by an input-output table. The table below is for the function y x 2. = +.
