Term
Horizontal Asymptote
Definition

 an imaginary line that an exponential function approaches as x goes to + infinity

 

Term
Composition of Functions
Definition

plugging one function into another; f(g(x)) or g(f(x))

Term
Constant Ratio
Definition

the fixed multiplier of a geometric sequence

Term
Exponential Function
Definition

function of the form f(x) = a(b)x

Term
Extrema
Definition

the highest or lowest value in a set

Term
Geometric Sequence
Definition

each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio

Term
Greatest Integer Function

Term
Piecewise Function
Definition

consists of different function rules for different parts of the domain

 

Term
Points of Discontinuity
Definition

undefined places on the graph where there are asymptotes, holes, jumps, or gaps; usually caused by division by 0 or disjoined pieces of a piecewise graph

 

Term
Step Function
Definition

a piecewise function consisting of only constant linear functions

Term
