Input And Output Values In Flow Diagrams And TablesWorked Examples1. Look At The Table Of Numbers Below:$\[ \begin{tabular}{|c|c|c|c|c|c|c|c|} \hline $x$ & -2 & -1 & 0 & 1 & 2 & 12 & $b$ \\ \hline $y$ & 9 & 5 & 1 & -3 & -7 & $a$ & -79
Understanding Input and Output Values
In mathematics, particularly in algebra and calculus, input and output values play a crucial role in understanding functions and their behavior. A function is a relation between a set of inputs, called the domain, and a set of possible outputs, called the range. The input values are the values that are fed into the function, while the output values are the results obtained after applying the function to the input values.
Input and Output Values in Tables
A table is a convenient way to represent input and output values of a function. In a table, the input values are listed in one column, and the corresponding output values are listed in another column. For example, consider the table below:
-2 | -1 | 0 | 1 | 2 | 12 | ||
---|---|---|---|---|---|---|---|
9 | 5 | 1 | -3 | -7 | -79 |
In this table, the input values are listed in the first column, and the corresponding output values are listed in the second column. For instance, when the input value is -2, the output value is 9.
Input and Output Values in Flow Diagrams
A flow diagram is a graphical representation of a function, showing the input values and the corresponding output values. In a flow diagram, the input values are represented by arrows pointing to the output values. For example, consider the flow diagram below:
+---------------+
| |
| Input: x |
| |
+---------------+
|
|
v
+---------------+
| |
| Output: y |
| |
+---------------+
In this flow diagram, the input value x is represented by an arrow pointing to the output value y.
Worked Examples
Example 1: Finding the Output Value
Suppose we have a function f(x) = 2x + 1, and we want to find the output value when the input value is 3. We can use the table below to find the output value:
1 | 2 | 3 | 4 | 5 | |
---|---|---|---|---|---|
3 | 5 | 7 | 9 | 11 |
From the table, we can see that when the input value is 3, the output value is 7.
Example 2: Finding the Input Value
Suppose we have a function f(x) = x^2 + 1, and we want to find the input value when the output value is 10. We can use the table below to find the input value:
-2 | -1 | 0 | 1 | 2 | |
---|---|---|---|---|---|
5 | 2 | 1 | 2 | 5 |
From the table, we can see that when the output value is 10, the input value is not listed. However, we can use the equation f(x) = x^2 + 1 to find the input value. Solving for x, we get x = โ(10 - 1) = โ9 = 3.
Example 3: Finding the Input and Output Values
Suppose we have a function f(x) = 2x - 1, and we want to find the input and output values when the input value is 2. We can use the table below to find the input and output values:
1 | 2 | 3 | 4 | 5 | |
---|---|---|---|---|---|
1 | 3 | 5 | 7 | 9 |
From the table, we can see that when the input value is 2, the output value is 3.
Conclusion
In conclusion, input and output values are essential in understanding functions and their behavior. Tables and flow diagrams are convenient ways to represent input and output values of a function. By using tables and flow diagrams, we can easily find the input and output values of a function, and understand the behavior of the function.
