If you are picking a President, VP, and Treasurer, that's permutations because the order of seating changes the role." jenna nolan math 30-1

Inverse Functions: $f^-1(x)$. Remember: switch $x$ and $y$, then solve for $y$.

Stretches vs. Compressions: A vertical stretch by a factor of 2 is different from a horizontal compression by a factor of $1/2$. They look the same on a graph, but the mapping rule is different.

Week 2 – Deep Remediation: Read only the "explanation" sections for those weak units. Do not skip examples. Redo every question you got wrong until you can explain why the right answer is right. Inverse Functions: $f^-1(x)$
