Across
- 2. The point where a line meets or crosses the y-axis
- 5. A letter or symbol used to represent a number.
- 9. The maximum or minimum value of a parabola, either in terms of y if the parabola is opening up or down, or in terms of x if the parabola is opening left or right.
- 10. A number multiplied by a variable.
- 14. of a quadratic equation The discriminant of a quadratic equation of the form ax 2 + bx+ c = 0, a ≠ 0, is the number b2 – 4ac.
- 15. quartile For a data set with median M, the third quartile is the median of the data values greater than M.
- 18. Number A number whose decimal form is nonterminating and nonrepeating. Irrational numbers cannot be written in the form a/b, where a and b are integers (b cannot be zero). So all numbers that are not rational are irrational.
- 20. The branch of mathematics that deals with relationships between numbers, utilizing letters and other symbols to represent specific sets of numbers, or to describe a pattern of relationships between numbers.
- 21. A mathematical phrase involving at least one variable and sometimes numbers and operation symbols.
- 23. Function A function with a constant rate of change and a straight line graph
- 24. Quartile (Q1) The “middle value” in the lower half of the rank-ordered data
- 25. A number, a variable, or a product of numbers and variables.
- 26. The set of x-coordinates of the set of points on a graph; the set of x-coordinates of a given set of ordered pairs. The value that is the input in a function or relation.
Down
- 1. function A function of degree 2 which has a graph that “turns around” once, resembling an umbrella–like curve that faces either right–side up or upside down. This graph is called a parabola.
- 3. the square Completing the Square is the process of converting a quadratic equation into a perfect square trinomial by adding or subtracting terms on both sides.
- 4. To replace one element of a mathematical equation or expression with another
- 6. Any mathematical sentence that contains the symbols > (greater than), < (less than), ≤ (less than or equal to), or ≥ (greater than or equal to).
- 7. Function A nonlinear function in which the independent value is an exponent in the function, as in y = ab^x
- 8. The point where a line meets or crosses the x-axis
- 11. Summary. Minimum, lower quartile, median, upper quartile, maximum.
- 12. Expression An algebraic expression with two unlike terms.
- 13. A change (positive, negative or constant) in data values over time.
- 16. The set of all possible outputs of a function.
- 17. Quartile (Q2) The median value in the data set
- 19. Number A number expressible in the form a/b or – a/b for some fraction a/b. The rational numbers include the integers.
- 22. The ratio of the vertical and horizontal changes between two points on a surface or a line
