A graphic and algebraic approach to finding inverse functions.

Make sense of problems and persevere in solving them.

Reason abstractly and quantitatively.

Model with mathematics.

Use appropriate tools strategically.

Attend to precision.

Look for and make use of structure.

Solve an equation of the form f(x) = c for a simple function f that has an inverse and write an expression for the inverse.
