Radicals, Powers, and Roots
Algebra II Terms
Get down with the lingo
BaseThe number an exponent is 'attached' to (what a leech) in its superscript. In a logarithm, it is located in the subscript.
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.
DomainThe set of all possible inputs for which the function is defined.
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 but never quite reaches 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 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 vertical line x = a if f(x) approaches +infinity or -infinity as x approaches a from right or left.
