The pattern rule that relates the input to the output is: Divide the input by 2. Then add 3. 1. Each table of values shows the input and output from a machine with 1 operation.
What is the rule for this input-output table?
An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (x-value) by 3 to find each output number (y-value).
Can an input have two outputs?
If a graph shows two or more intersections with a vertical line, then an input (x-coordinate) can have more than one output (y-coordinate), and y is not a function of x.
Can one input have two outputs?
By definition, the inputs in a function have only one output. The input 1 has two outputs: 0 and 5….
| x | y |
|---|---|
| 1 | 0 |
| 1 | 5 |
| 2 | 0 |
What are the inputs and outputs of a computer?
An input device is something you connect to a computer that sends information into the computer. An output device is something you connect to a computer that has information sent to it.
What is the formula for patterns?
A linear number pattern is a list of numbers in which the difference between each number in the list is the same. The formula for the nth term of a linear number pattern, denoted an, is an = dn – c, where d is the common difference in the linear pattern and c is a constant number.
What is input and output number?
Input is the number in the first column of the table. This is the number that you start with to follow the rule if the rule is given. You would also use this number to figure out what the rule is if it is not given. You always start with input. Output is the end number or the answer to the math equation.
How to extend an input / output pattern using a two step rule?
We need to be able to complete the input/output table using the rule.” Teacher points to the first row of the table and says, “If I put 8 into the number machine, I would multiply 8 by 2 to get 16 and then add 4 to get 20.” Teacher writes 8×2=16+4=20 on the board and says, “Really, you just have to follow the rule.
What are the input and output numbers on a chart?
These charts show a pattern of “input” and “output” numbers; students are asked to determine the relationship between the input and the output (which will be simple addition or subtraction) and to fill in the missing numbers. Numbers up to 100 are used.
When to use a rule in an input / output table?
By the end of the lesson, you will be able to use a rule to complete an input/output table on your own.” Direct Instruction (10 – 12 min): Teacher posts the Example Problem on the board and says, “When we look at this problem, we should be reminded about what we learned yesterday when we were determining the rule.
