- 1. Another word for average. Mean almost always refers to arithmetic mean. In certain contexts, however, it could refer to the geometric mean, harmonic mean, or root mean square.
- 3. The symbols [and].
- 6. of a Line- A number which is used to indicate the steepness of a line, as well as indicating whether the line is tilted uphill or downhill. Slope is indicated by the letter m.
- 10. A quantity that can change or that may take on different values. Variable also refers to a letter or symbol representing such a quantity.
- 12. A polygon with seven sides. Some authors also use the name heptagon instead of heptagon.
- 13. four sections into which the x-y plane is divided by the x- and y-axes.3. Axes- Plural of axis.
- 14. A point at which a graph intersects the y-axis.
- 15. The set of values of the independent variable(s) for which a function or relation is defined. Typically, this is the set of x-values that give rise to real y-values. Function- A relation for which each element of the domain corresponds to exactly one element of the range. For example, is a function because each number x in the domain has only one possible square root. On the other hand, is not a function because there are two possible values for any positive value of x.
- 18. The mathematics of working with variables.
Down
- 1. The number that occurs the most often in a list.
- 2. A conic section which is essentially a stretched circle.
- 4. The number multiplied times a product of variables or powers of variables in a term. For example, 123 is the coefficient in the term 123x3y.
- 5. x in the expression ax. For example, 3 is the exponent in 23
- 7. Root- A non negative number that must be multiplied times itself to equal a given number. The square root of x is written or x½. For example, since 32 = 9.
- 8. A point at which a graph intersects the x-axis. The x-intercepts of a function must be real numbers, unlike roots and zeros.
- 9. A transformation in which a figure grows larger. Dilations may be with respect to a point (dilation of a geometric figure) or with respect to the axis of a graph(dilation of a graph).
- 11. An equation, graph, or data that can be modeled by a degree 2 polynomial.
- 16. curve that is somewhat heart shaped. A cardioid can be drawn by tracing the path of a point on a circle as the circle rolls around a fixed circle of the sameradius. The equation is usually written in polar coordinates.
- 17. Tree- A structure used to find the prime factorization of a positive integer.
- 19. The set of y-values of a function or relation. More generally, the range is the set of values assumed by a function or relation over all permitted values of the independent.
