Miss Smith's math tutorial covers writing equations for functions using linear, quadratic, and exponential patterns. The video explains how to identify these patterns from data tables and use calculators to determine equations. It also introduces the R-squared value for identifying the best fit pattern in complex data sets.

What is the main focus of this video tutorial?

• Understanding exponential growth

• Solving linear equations

• Writing equations of functions

• Graphing quadratic functions

• y = a / x

How can you use the R-squared value in determining the best fit for a data set?

• By finding the value closest to zero

• By finding the lowest positive value

• By finding the value closest to one

• By finding the highest negative value

What does an R-squared value of 1 indicate?

• A perfect exponential fit

• A perfect quadratic fit

• No correlation

• A perfect linear fit

What should you do if the R-squared value is not automatically shown on your calculator?

• Reset the calculator

• Turn on the diagnostic setting

• Update the calculator software

• Change the battery
