Algebra II Terms

Get down with the lingo

Base


Coefficient


Complex Number

Any number in the form a + bi where a and b are real numbers. In English, it's a number created by the addition of one real and one imaginary number.

Domain

The set of all possible inputs for which the function is defined.

Exponent


Horizontal Asymptote

A way to graphically describe the end behavior for a curve that approaches but never quite reaches a certain outputted y-value.

Imaginary Number

This is defined as the square root of -1.

Index


Irrational Number

This is a number that cannot be written as the quotient of two integers.

Radical

Also called a root, basically anything that uses √. It doesn't have anything to do with trees or plants unless those plants are oddly mathematically inclined.

Radicand


Range

The set of all possible output values of the function.

Rational Number

A number that can be written as the quotient of two integers. The denominator cannot be zero.

Real Number

The set of numbers including both the rational and irrational numbers.

Simple Radical Form

The form of a number that has no radicals in the denominator, or as we like to say, no radicals in the basement. Could you imagine having a radical in your basement? You'd want them out of there, too.

Vertical Asymptote

A type of discontinuity typically marked by a dashed line, on either side of the vertical asymptote the corresponding curve will approach either negative or positive infinity.
