Mrs. Ga's lesson covers identifying linear, quadratic, and exponential data, and finding regression models for these data types using a graphing calculator. The video includes a warm-up exercise, practical examples, and problem-solving activities to reinforce learning. Students learn to analyze data from tables and scatter plots, and apply regression models to find the best fit for data trends.

What types of data are being identified in this lesson?

• Linear, Logarithmic, Polynomial

• Linear, Cubic, Logarithmic

• Quadratic, Cubic, Exponential

• Linear, Quadratic, Exponential

Why is a graphing calculator necessary for this lesson?

• To draw graphs manually

• To perform complex calculations

• To find regression models

• To solve algebraic equations
