A value ƒ(c) is an absolute maximum value of ƒ if ƒ(c) ? ƒ(x) for all x in the domain of ƒ.

The opposite of a + bi, or -a - bi

See Exponential function, Logarithmic function, nth power of a.

In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n - k2!pk11 - p) n-k where p is the probability of the outcome occurring once

A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

The number r2 or R2 that measures how well a regression curve fits the data

An expression a + bi, where a (the real part) and b (the imaginary part) are real numbers

A letter or symbol that stands for a specific number,

The factor Ae-a in an equation such as y = Ae-at cos bt

The largest exponent on the variable in any of the terms of the polynomial (function)

A nonnegative number that specifies how off-center the focus of a conic is

Outcomes of an experiment that have the same probability of occurring.

The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

logb Rc = c logb R, R 7 0.

For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

Use a graphical method, including use of a hand sketch or use of a grapher. When appropriate, the approximate solution should be confirmed algebraically
