Every question here is an SAT Math question that Desmos regression solves fast. Try it in the calculator first, then open its step-by-step Desmos solution to check your setup. New to Desmos regression? Start with the SAT Desmos guide.
The 50 questions run in five sections, in the order the Desmos course teaches them:
- Regression from a table: fit linear, quadratic and exponential models to data, then predict from them.
- Custom regression with one unknown: find a missing constant from a value the function has to hit.
- Custom regression with several conditions: solve for two or three constants at once.
- Best-fit lines and residuals: work with models that don't pass through every point.
- Circle regression: find a circle's center, equation or area from points on it.
Questions get harder within each section, and each section's heading links the lesson that teaches it.
