Final answer:
When testing a function, you can use a table or mapping/graphing approach. Tables allow for systematic testing of different input values and their corresponding outputs, while mapping/graphing provides a visual representation of the function's behavior and patterns.
Step-by-step explanation:
When testing a function, there are a couple of different approaches you can take. One approach is to create a table of inputs and corresponding outputs. This involves choosing different values for the input variable and determining the corresponding output. For example, if the function is f(x) = 2x, you could choose input values of 1, 2, and 3, and calculate the corresponding outputs of 2, 4, and 6. Another approach is to use mapping or a graph to visualize the function. You can plot the input values on the x-axis and the corresponding output values on the y-axis. This can help you see the pattern and behavior of the function more easily. The advantage of using a table is that it provides a systematic way to test different input values and observe the corresponding outputs. It allows you to see how the function behaves for different inputs. On the other hand, mapping or graphing the function can give you a visual representation of the function, making it easier to understand its behavior and any patterns or trends.
