*a*and

*b*are real numbers. In English, it's a number created by the addition of one real and one imaginary number.

### Domain

### 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.### People who Shmooped this also Shmooped...
