finial

4. a quantity that can be described by a single element of a number field, such as a real number, often accompanied by units of measurement, as in "10 cm"
9. a transformation is a function f that maps a set X to itself, i.e. f: X → X. In other areas of mathematics, a transformation may simply refer to any function, regardless of domain and codomain.
10. line through a scatter plot of data points that best expresses the relationship between those points
12. a parent function is the simplest function of a family of functions that preserves the definition of the entire family.
15. polynomial that is the sum of two terms, each of which is a monomial. It is the simplest kind of polynomial after the monomials
16. a fixed reference line for the measurement of coordinates.
17. In set theory and its applications to logic, mathematics, and computer science, set-builder notation is a mathematical notation for describing a set by enumerating its elements, or stating the properties that its members must satisfy
19. Vertical stretch occurs when a base graph is multiplied by a certain factor that is greater than 1. This results in the graph being pulled outward but retaining the input values (or x). When a function is vertically stretched, we expect its graph's y values to be farther from the x-axis.
20. a statistical measure of the strength of the relationship between the relative movements of two variables.

1. An interval is unbounded if both endpoints are not real numbers. Replacing an endpoint with positive or negative infinity—e.g., (−∞,b] —indicates that a set is unbounded in one direction, or half-bounded.
2. an assignment of values to the unknown variables that makes the equality in the equation true.
3. a solution of a system in three variables
5. any one of the distinct objects that belong to that set.
6. squeezing of the graph toward the x-axis.
7. is one of the basic operations defining a vector space in linear algebra.
8. the conjugate is where you change the sign ( to minus, or minus to ) in the middle of a problem
11. a point or value that marks the end of a ray or one of the ends of a line segment or interval.
13. a translation is a geometric transformation that moves every point of a figure or a space by the same distance in a given direction.
14. defined as the minimum number of coordinates needed to specify any point within it.
18. a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns.
