Across
- 1. root The cube root of a, written 3√a, is the number whose cube is a. That is, (3√a)3=a.
- 6. A single fixed number (unlike a variable, whose value can vary).
- 7. The bottom number or expression in a fraction.
- 9. fraction A fraction in which the numerator is larger than the denominator.
- 11. A constant that a variable or expression is multiplied by.
- 15. sequence A sequence of numbers in which each number can be computed by adding the same amount to the previous number.
- 16. Rectangles of equal width above a number line, where each rectangles’s height shows the number of data values in that portion of the number line.
- 17. growth Increasing rapidly due to a variable in an exponent, such as in y=2x.
- 19. An expression that is used to compute a value.
- 20. An image formed by plotting the solutions to an equation or inequality, or some other set of pairs of numbers, on a coordinate plane. To graph an expression containing the variable x, set y equal to that expression.
Down
- 2. In a power, the number of times the base is multiplied by itself.
- 3. A number that is raised to a power.
- 4. The most common value in a collection, or “modes” if more than one are tied.
- 5. The study of mathematical symbols and the rules for manipulating those symbols.
- 8. A straight line, or an equation or expression whose graph is a straight line. If m and b are constants, then mx+b is a linear expression, and a function f defined by f(x)=mx+b is a linear function.
- 10. The middle number in an ordered list of data values. If there are an even number of values, the median is halfway between the two middle numbers in the list.
- 12. The average of a collection of data values. This can be computed by adding all the values and then dividing by the number of values.
- 13. A collection of related measurements.
- 14. plot A diagram showing data values as dots above a number line.
- 18. number A number that cannot be written as a fraction.
