- 2. For numbers a, k and b ≠ 0, the function f(t) = (ab)^ t/k is called an exponential function. The number a = f(0) is the initial value, b is the base and k is a constant related to growth rate or period.
- 4. Members of a set.
- 8. A collection of information, frequently in the form of numbers.
- 11. The set of input values in a function.
- 13. the horizontal plane of a graph in a Cartesian coordinate system
- 15. what comes out of the function.
- 16. Two inequalities are equivalent if they have the same solution set.
- 17. a number that cannot be expressed as a fraction for any integers
- 18. Where lines cross over (where they have a common point).
- 19. a number that is raised to a certain power
- 22. the number you feed into the expression
- 23. a transformation, which is used to resize the object.
- 25. a data point that lies outside the overall pattern in a distribution.
- 27. The third power of a number.
- 28. changes in the output do not change in direct proportion to changes in any of the inputs.
- 30. a branch of mathematics in which arithmetic operations and other formal manipulations are applied to abstract symbols rather than specific numbers.
- 31. the factor that we can multiply by itself to get that number
- 32. a measure of its steepness.
- 33. any number that can be written as a fraction, where both the numerator (the top number) and the denominator (the bottom number) are integers, and the denominator is not equal to zero.
- 34. Suppose that n is a whole number. Then, for any number x, the nth power of x, or x to the nth power, is the product of n factors of the number x. This number is usually written x^n. The number x is usually called the base of the expression x^n, and n is called the exponent.

- 1. The expression b² −4ac that appears under the radical sign in the Quadratic Formula.
- 3. For real variables x and y, y varies directly with x if y = Kx or yx = K for a constant K, K ≠ 0. K is called the constant of proportionality.
- 5. A math sentence using the equal sign to state that two expressions represent the same number.
- 6. The variable in a function representing the elements of the range; the output values.
- 7. Expressions that have the same numerical value for given values of the variables.
- 9. See System of Equations
- 10. the point where a graph crosses the y-axis
- 12. The degree of a term is the sum of the exponents of the variables. The degree of a polynomial is the highest degree of any of its terms. If it contains no variables its degree is 0 if it is non-zero, and undefined if the polynomial is zero.
- 14. a data point that lies outside the overall pattern in a distribution.
- 16. statement of equality between two expressions consisting of variables and/or numbers.
- 20. Two equations are equivalent if they have the same solution or solution set.
- 21. For real number x and y, y is the cube root of x, (written √3 x ), if y³ = x.
- 24. When two lines are crossed by another line (which is called the Transversal), the angles in matching corners
- 26. a set of points plotted on a horizontal and vertical axes.
- 29. there are no factors of a number.
