Algebra II Terms
Get down with the lingo
BaseThe number an exponent is "attached" to (what a leech). For example, bn has a base of b.
CoefficientA number multiplied by a variable. In the term 23x, that'd be the number 23.
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.
DomainAll the values x can take in a function. It's like x is a little king, and the domain is, well, its domain.
ExponentThe number that indicates which power to raise the base to. In the term bn, the exponent is n.
Horizontal AsymptoteA way to graphically describe the end behavior for a curve that approaches (and sometimes crosses) a certain outputted y-value.
Imaginary NumberThis is defined as the square root of -1.
IndexTiny Tim-sized number sitting in the radical √. For instance, 3 in the 3√.
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.
RadicandThe expression or number inside a radical.
RangeThe set of all possible outputs (y-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 FormAn expression that's been fully reduced to prime factors and 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 vertical line, x = a, where f(x) approaches ± ∞ as x approaches a from the right or left.
