Get down with the lingo
Complex NumberAny 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.
DomainThe set of all possible inputs for which the function is defined.
Horizontal AsymptoteA way to graphically describe the end behavior for a curve that approaches but never quite reaches a certain outputted y-value.
Imaginary NumberThis is defined as the square root of -1.
Irrational NumberThis is a number that cannot be written as the quotient of two integers.
RadicalAlso 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.
RangeThe set of all possible output values of the function.
Rational NumberA number that can be written as the quotient of two integers. The denominator cannot be zero.
Real NumberThe set of numbers including both the rational and irrational numbers.
Simple Radical FormThe 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 AsymptoteA 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.
