- 6. Any mathematical calculation or formula combining numbers and/or variables using sums, differences, products.
- 8. best teacher in tstem
- 12. To find the value of a numerical or algebraic expression
- 13. is the number of different digits or combination of digits and letters that a system of counting uses to represent numbers.
- 15. when a number is raised to a power, the number that is used as the factor
- 16. For a square matrix A, the inverse is written A-1. When A is multiplied by A-1 the result is the identity matrix I. Non-square matrices do not have inverses.
- 20. the rate of growth is directly proportional to the amount present.
- 21. states you can add or multiply in any order
- 23. A function with a graph that goes up as it is followed from left to right. For example, any line with a positive slope is increasing.
- 24. has two logs, each having the same base, set equal to each other
- 28. An expression that contains at least one variable
- 30. where x represents a variable, and a, b, and c are constants,
- 32. a function of the form y=abx, where a does not equal 0, b>0, and b does not equal 1
- 35. is one in which a variable occurs in the exponent,
- 36. allows you to rewrite a logarithm in termsof logs written with another base
- 37. a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression
- 39. one period to another in percentage terms, always decreasing.
- 41. a logarithm to the base
- 42. is any measurement that there is 1 of. And 1 m/s (one meter per second) is also a

- 1. The lowest point over the entire domain of a function or relation.
- 2. decay exponentially
- 3. The use of exponents.
- 4. Decay rate of decay is directly proportional to the amount present.
- 5. The highest point over the entire domain of a function or relation.
- 7. variable with a number attached
- 9. is the simplest function of a family of functions. For the family of quadratic functions, y = ax2 + bx + c
- 10. a quantity representing the power to which a fixed number (the base) must be raised to produce a given number.
- 11. A quantity that can change or that may take on different values. Variable also refers to a letter or symbol representing such a quantity.
- 14. that is the inverse of an exponential function (as y = ax or y = ex) so that the independent variable appears in a logarithm.
- 17. A line about which a plane figure is rotated in three dimensional space to create a solid or surface.
- 18. A rectangular (or square) array of numbers. Matrices can be written using brackets or parentheses
- 19. An equation of the form ax 2 + bx + c = 0 ,
- 22. you can set the exponents equal to solve for x.
- 25. The function obtained by switching the x- and y-variables in a function. The inverse of function f is written f -1.
- 26. an activity or purpose natural to or intended for a person or thing.
- 27. a mathematical statement that two expressions are equal
