Identifying Linear, Quadratic, and Exponential Models

The video tutorial explains the differences between linear, quadratic, and exponential models. Linear models have constant differences between values, quadratic models have constant second differences, and exponential models have constant ratios between values. The tutorial provides examples and methods to identify each model type based on these characteristics.

What are the three types of models discussed in the video?

• Linear, Quadratic, Polynomial

• Linear, Quadratic, Exponential

• Linear, Polynomial, Exponential

• Quadratic, Exponential, Logarithmic

How can you identify a linear model?

• By checking if the values are all the same

• By checking if the differences of differences are consistent

• By checking if the ratios are consistent

• By checking if the differences are consistent

In a linear model, what is the pattern of differences?

• They are consistent

• They are negative

• They are zero

• They are inconsistent

What is the main focus when identifying a linear model?

• The actual numbers

• The differences between numbers

• The ratios

• The differences of differences

What is the difference between a linear and a quadratic model?

• Linear models have consistent differences, quadratic models have changing differences

• Linear models have changing differences, quadratic models have consistent ratios

• Linear models have consistent ratios, quadratic models have consistent differences

• Linear models have consistent differences, quadratic models have consistent values

In a quadratic model, what is consistent?

• The differences

• The ratios

• The values

• The differences of the differences

Which model is identified by consistent differences of differences?

• Exponential

• Quadratic

• Logarithmic

• Linear

What is the pattern of differences in a quadratic model?

• They are consistent

• They are zero

• They are inconsistent

• They are negative

What is the pattern of differences of differences in a quadratic model?

• They are zero

• They are negative

What is the main focus when identifying a quadratic model?

• The differences between numbers
