Understanding Linear Functions

The video tutorial explains how to analyze a linear function, specifically f(x) = 2x, by identifying its slope and intercepts. It describes the slope-intercept form of a linear function and demonstrates how to find the slope and vertical intercept. The tutorial also shows how to plot the vertical and horizontal intercepts on a graph and how to graph the line using the slope. The video concludes with a visual representation of the line passing through the calculated points.

What is the given linear function in the video?

• f(x) = 2x + 1

• f(x) = 3x

• f(x) = x + 2

• f(x) = 2x
