- 2. - In mathematics, an _____ is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
- 7. - the total number of digits or sometimes, the combination of digits and letters that is used to express numbers in a number system.
- 8. sequence: A sequence of numbers in which each number can be computed by adding the same amount to the previous number.
- 9. Function - An ______ function is a mathematical function that represents the relationship between an input and output.
- 10. - a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
- 13. Progression - An ______ progression (AP) is a sequence of numbers where the difference between each term is constant. This constant difference is called the common difference.
- 14. like terms: Using the distributive law to add any two multiples of an expression such as x. For example, you can simplify 4x+5x into 9x.
- 17. function: A function f with f(x)=f(−x) for all x. f(x)=xn is an even function if n is an even integer. A function is even if and only if its graph has the y-axis as an axis of symmetry.
- 19. - an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
- 20. - In mathematics, the _____ of a function is the set of inputs that the function accepts. It can also be defined as the set of all possible values that qualify as inputs to a function.
- 23. - an equality that holds true regardless of the values chosen for its variables

- 1. - A ______ is a quantity or function that can take on any given value or set of values. It can also be defined as a characteristic, number, or quantity that can be measured or counted.
- 2. Elements - In mathematics, the concept of an _____ element generalizes the concepts of opposite (−x) and reciprocal (1/x) of numbers.
- 3. - a function which takes one or more inputs (named operands) and produces an output.
- 4. plot: A diagram showing data values as dots above a number line.
- 5. A dilation by a positive number r about a point A is a transformation that moves each other point B along the ray from A that passes through B, and multiplies distances from A by r. A is called the center of the dilation.
- 6. - In mathematics, a _____ is a number or symbol that has a fixed value. It's a value or number that never changes in expression.
- 10. root: The cube root of a, written 3√a, is the number whose cube is a. That is, (3√a)3=a.
- 11. - _______ is a mathematical process that involves writing a number or other mathematical object as a product of several factors.
- 12. - a number that is not a fraction; a whole number.
- 15. - a real number that cannot be expressed as a ratio of integers.
- 16. function: ceiling(x) is the closest integer which is greater than or equal to x.
- 18. Value - In mathematics, _____is the non-negative value of a real number without regard to its sign. It can be thought of as the distance from zero along the real number line.
- 21. of symmetry: A line that you can flip (or reflect) a graph across that results in the same graph.
- 22. fit line: When the points on a grid are not all on a straight line, but seem to have a somewhat linear pattern, you can find a line that is the “best fit” (closest) to the points.
