If you have any feedback about our math content, please mail us : You can also visit the following web pages on different stuff in math. Take a look at this tutorial! You can tell if a table is linear by looking at how X and Y change. A linear function results in a graph that is a straight line, and the values of f(x) and x written as a table show a one to one correspondence. To find if the table follows a function rule, check to see if the values follow the linear form . Solve as follows. In other words, it is the input value when the output value is zero. Now he intends to find value of slope, i.e. For example, consider the function … How To Write a Linear Equation From a Function Table - YouTube Example 3 : Determine whether each set of data displays exponential behavior.
