Checkpoint Quiz 2

This checkpoint covers Inverse Functions, Composite Functions, and Working with Functions — Synthesis (Lessons 6–8).

🎯

📋

Quick Review

Inverse functions: swap $x$ and $y$, solve for $y$. Remember to restrict domains for non-one-to-one functions like quadratics.
Domain of inverse = range of original; range of inverse = domain of original.
Composite functions: $(f \circ g)(x) = f(g(x))$. Work from the inside out.
Domain of composite: $x$ must be in the domain of $g$, AND $g(x)$ must be in the domain of $f$.
