Identifying Linear, Quadratic, and Exponential Functions

Mrs. Graham introduces a lesson on identifying linear, quadratic, and exponential functions. She explains how to recognize these functions using tables and simple subtraction, emphasizing the importance of consecutive integers in X values. The video includes detailed explanations of each function type, examples, and practice problems to help students understand and apply the concepts.

What should you do if you don't understand something in the lesson?

• Wait until school reopens

• Guess the answers to homework

• Ignore the confusion and continue

• Contact the teacher via email or Google Classroom

What is the form called that linear functions are normally written in?

• Ratio form

• Standard form

• Slope-intercept form

• Quadratic form

What should you use if X values are not consecutive?

• Ignore the data

• L1 and L2 on a calculator

• Simple addition

• A standard calculator

What is the significance of consecutive integers in X values?

• They are irrelevant to function identification

• They indicate a quadratic function

• They are necessary for using simple subtraction

• They suggest the use of a graphing calculator

If the first difference of the Y values is constant, what type of function is it?

• Undefined

• Exponential

• Linear

• Quadratic

What does the 'B' term represent in the slope-intercept form of a linear equation?

• The exponential base

• The quadratic coefficient

• The intercept

• The slope

What indicates a quadratic function when analyzing differences?

• Variable second difference

• Non-consecutive X values

• Constant second difference

• Constant first difference

How can you correct a mistake when identifying function types?

• All of the above

• Erase the incorrect data

• Use a different set of data

• Adjust the data to fit the model

What is typically used to identify exponential functions?

• Subtraction of Y values

• Ratio of consecutive Y values

• Addition of X values

• None of the above

What does a constant ratio in Y values indicate?

• Exponential function

• Quadratic function

• Linear function

• No specific function
