Lesson Plan

Read f^-^1(b) from a table of f by finding the row where f(a) = b and reporting a

Read f^-^1(b) from a graph of f by finding the point where y = b on the graph and reading the corresponding x-value

Construct a table of f^-^1 by swapping the input and output columns of a table for f

Sketch the graph of f^-^1 by reflecting the graph of f over y = x

Determine whether the inverse function exists from the table or graph (no repeated outputs)

Interpret inverse values in context: if f(t) gives population at time t, then f^-^1(P) gives the time when population reaches P
