Across
- 4. A complex number. Represented with the letter i.
- 6. The point where two or more lines, rays, or edges meet. The max or min on a quadratic equation.
- 12. The total distance from zero on the number line. Cannot be negative.
- 15. The number in front of a variable. If there is no number, there is an implied 1.
- 16. Special rule that relates two sets of numbers. Every input produces exactly one output.
- 17. A symmetrical U-shaped survey. This is formed by graphic a quadratic equation.
- 19. Involves only addition, subtraction, multiplication, and non-negative integers. Consists of variable and coefficients.
Down
- 1. Constant rate of change. Rise over run.
- 2. Where a graph, line, or curve intersects the vertical Y-axis.
- 3. The element that's is greater than or equal to all other elements in that set.
- 4. A variable in an equation that represents a quantity being manipulated or chosen. Does not depend on other variables.
- 5. A notation indicating the number of times a base number is multiplied by itself. It defines the power to which base is raised.
- 7. Dictated by the leading term of the function.
- 8. Inverse operation of squaring a number. A number that can be multiplied by itself to equal the original number.
- 9. The difference between the highest and lowest values in a given set of numerical data.
- 10. The value you multiply a number by to get 1.
- 11. A way to solve a system of linear equations. Done by isolating one variable in one equation and substituting its equivalent expression.
- 13. A letter that represents a number in an expression or equation. X, Y, and Z are frequently used.
