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.

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.
