Understanding Linear Functions

The video tutorial explains how to complete a table for the equation f(x) = 6x - 5 by calculating function outputs for given x values. It demonstrates how to plot these points on a graph to visualize the function. The tutorial emphasizes the importance of using multiple points to ensure accuracy in graphing a linear function.

What is the equation given in the task to complete the table?

• f(x) = 5x + 6

• f(x) = 6x - 5

• f(x) = 5x - 6

• f(x) = 6x + 5
