show | Abscissa
🗑
|
||||
The distance from x to the origin on the real number line. Because it represents distance, absolute value is never less than zero. | show 🗑

|
||||
Numeric or algebraic input into an algorithm, nth function, or other defined function. | show 🗑
|
||||
A sequence in which successive terms have a common difference. It can be written as an=a1+(n-1)d where "an" is the nth term of the sequence, "a1" is the first term and "d" is the common difference. | show 🗑
|
||||
show | Arithmetic series

||||
show | Binary Operation
🗑
|
||||
show | Binomial
🗑
|
||||
A set is said to be closed under some operation if the operation on members of the set produces a member of the set. A set that is closed under an operation or collection of operations is said to satisfy a closure property. | show 🗑

🗑
|
||||
The non-zero (usually denoted k) in a direct variation (y=k/x), an indirect variation (y= k/x ) or a joint variation (z=kxy). | show 🗑
|
||||
A function f is continuous at a point (x, y) if it is defined at that point and passes through that point without a break. | show 🗑
|
||||
A function f is decreasing on an interval if and only if for every a and b in the interval, f(a) > f(b) whenever a < b. | show 🗑

show | Indirect (inverse) variation
🗑
|
||||
show | x-intercept and y-intercept
🗑
|
||||
A relationship that exists when a quantity varies directly with the product of two or more quantities y = kxy. | show 🗑
