We say that x is the inverse of a, modulo n, if ax is congruent
to 1 (mod n). Use this definition to find the inverse, modulo 13,
of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.
Show by example that when the modulus
is composite, that not every number has an inverse.

notation.
(b) Find the inverse of the function ff.
(c) Find the function g/kg/k and its domain using the interval
notation.
(d) Simplify the expression
[k(x+h)−k(x)]/h[k(x+h)−k(x)]/h.
