- 2. the process of finding the equation of the parabola that best fits a set of data.
- 6. notation for representing an interval as a pair of numbers. The numbers are the endpoints of the interval. Parentheses and/or brackets are used to show whether the endpoints are excluded or included.
- 8. A value, or values, we can put in place of a variable (such as x) that makes the equation true.
- 9. a value that can be substituted for the variable in order that the equation holds. In other words it is a "solution" of the equation. It is called a ANSWER if it is also a real number.
Down
- 1. a function is a real number that makes the value of the function equal to zero
- 3. a polynomial is a quantity that depends on the coefficients and determines various properties of the roots.
- 4. a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
- 5. compares two values, showing if one is less than, greater than, or simply not equal to another value.
- 7. a number or algebraic expression that divides another number or expression evenly
- 8. A strategy for solving systems of equations that include solving for one variable and using that solution to find the other variable.
