1Product Rule(du/dx)(v) + (u)(dv/dx)
2Chain ruledy/dx = dy/du * du/dx
3When is a function one to one?When every y value corresponds to only one x value
4When is a function many to oneWhen some y values correspond to more than one x value
5What mapping is not a functionone to many
6What is the domain of a function?The possible input values
7What is the range of a function?The possible output values
8What are the three ways of expressing a composite function?f(g(x)) or fg(x) or f o g(x)
9What does f o f(x) can be written as?f^2(x)
10How do you find the inverse function of a function?Rearrange f(x) so that x is in term of y. Swap the x's and y's
11What line is the reflection between f^-1(x) f(x).y = x
12What is the relation between the domains and ranges of f^-1(x) and f(x)The domain of f^-1(x) is the range of f(x). The range of f^-1(x) is the domain of f(x).
