Exploring Linear and Nonlinear Functions

The video tutorial explains how to determine if a relationship is a linear function using a table, graph, and equation. It uses the example of photos taken and memory left on a camera chip. The tutorial demonstrates plotting data points, identifying a constant rate of change, and formulating the linear equation. It concludes with a verbal description of the function and hints at future topics on non-linear functions.

What is the main problem discussed in the video?

• Understanding non-linear functions

• Representing linear functions using a table

• Calculating the total memory of a camera

• Finding the number of photos a camera can take

What is the equation derived to represent the linear relationship?

• y = 512 + 3x

• y = 512 - 3x

• y = 3x - 512

• y = 3x + 512

How is the equation described in words?

• The memory left is 512 plus three times the number of photos taken

• The memory left is 512 minus three times the number of photos taken

• The memory left is three times the number of photos taken plus 512

• The memory left is three times the number of photos taken minus 512

What is the purpose of describing the relationship in words?

• To make it easier to understand

• To confuse the students

• To check for errors

• To create a new equation
