  1. 2. The square root of a number π‘₯, is a number, 𝑦 such that 𝑦2 = π‘₯; in other words, the square root of a number is a number whose square is 𝑦 βˆ™ 𝑦.
  2. 6. An imaginary straight line that divides a shape into two identical parts, thereby creating one part as the mirror image of the other part.
  3. 8. A straight line that best represents the relationship between two variables plotted on a scatter plot.
  4. 9. 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, etc. The resulting number when you multiply a number times itself. EX: 4 X 4 = 16
  5. 10. The set of input values for which the function is defined.
  6. 13. In an equation or inequality, a number that can be substituted for the variable to make that equation or inequality true.
  7. 16. A number between -1 and 1 that tells you if you have a strong or weak correlation. It also lets you know if it is a positive or negative correlation.
  8. 18. Ax + By = C, with NO fractions, NO decimals, and A is positive!
  9. 22. Element in a sum, difference, or sequence.
  10. 23. the OUTPUT or RESULT in a situation or problem. It's the variable YOU CANNOT control. It's the Y variable.
  11. 24. A letter or number representing a numerical quantity that multiplies a term.
  12. 25. The highest point of a parabola.
  13. 27. A measure of variation in a set of numerical data, the interquartile range is the distance between the first and third quartiles of the data set.
  14. 28. A relationship where one variable's change directly results from the change in another variable.
  15. 30. The point where a parabola crosses its axis of symmetry, or an end of a side of a polygon, or the corner point of an angle.
  16. 31. The asymmetry or distortion of a distribution, specifically how the data is distributed around its center.

  1. 1. The difference between the lowest and highest values in a set of data."
  2. 3. The values of x where an expression is zero. These are the x-coordinates of the x-intercepts of the expression’s graph. For a polynomial expression, these are usually called roots.
  3. 4. The basic equation where the graph is free from any transformation.
  4. 5. A polynomial function with a degree of 2, having at least one term with one or more variables having the highest exponent of 2.
  5. 7. A data point that does not fit in with the rest of the data. Defined as Q3+1.5xIQR or Q1-1.5xIQR.
  6. 11. Observable events or relationships that can be described and understood using mathematical models and concepts.
  7. 12. "(Algebra) The set of outputs the function achieves when it is applied to its whole set of outputs.
  8. 14. A point on a 2-dimensional plane is described by a pair (x,y). The coordinate x is given by the labels below the grid, and the coordinate y is given by the labels to the left of the grid.
  9. 15. Relating to a parabola.
  10. 17. Rewriting the equation x2+2mx=n as (x+m)2=n+m2 so that it can be more easily solved.
  11. 19. The lowest point on a parabola.
  12. 20. the INPUT or CAUSE in a situation or problem. It's the variable YOU CAN control. It's the X variable.
  13. 21. Describes how a function behaves as its input approaches positive or negative infinity.
  14. 26. A graph in the coordinate plane representing a set of bivariate data
  15. 29. a line that a given curve continually approaches but does not meet
