**a**
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. For example, $f(x) =2 x^3$ or $f(x) = (x+1)/(x-1)$ for $x \neq 1$.

**b**
Verify by composition that one function is the inverse of another.

**c**
Read values of an inverse function from a graph or a table, given that the function has an inverse.

**d**
Produce an invertible function from a non-invertible function by restricting the domain.
