About this activity
Construct inverse functions by reflecting points across y = x, determine equations algebraically, and restrict domains for one-to-one functions.
What students learn
- Reflect points and curves across the line y = x to produce inverse relations
- Determine algebraic equations of inverse functions by swapping variables and solving for y
- Restrict the domain of quadratic and radical functions so their inverses are valid functions
- Validate inverse relations using the Vertical Line Test and horizontal line analysis
