A function m is a [Select] The [Select] of functions f and g if m(x) = f[g(x)]. of m is the set of all numbers such that x is in the domain of g, and g(x) is in the domain of f.

Let f:Z>Z be a function given by f(x) = -3x + 1. Recall that Z = the set of all integers, that is, Z = {.,-2,-1, 0, 1, 2,...

Consider the function: g(x) = with the domain R\(9} (i.e. all real numbers except 9) and the image R\{1} (i.e. all real numbers except 1). Find the expression for the inverse function g(x). Select one: O (5+9x)/(x+1) O 5+9x (x-9)/(x+5) O not in the list (5+9x)/(x-1)

A function that is [Select] interval [a, b] has [Select] on a [Select] on that interval.
