  1. 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.
  2. 6. In an equation or inequality, a number that can be substituted for the variable to make that equation or inequality true.
  3. 7. A letter or number representing a numerical quantity that multiplies a term.
  4. 10. A graph in the coordinate plane representing a set of bivariate data
  5. 13. An imaginary straight line that divides a shape into two identical parts, thereby creating one part as the mirror image of the other part.
  6. 14. Describes how a function behaves as its input approaches positive or negative infinity.
  7. 16. The asymmetry or distortion of a distribution, specifically how the data is distributed around its center.
  8. 17. A data point that does not fit in with the rest of the data. Defined as Q3+1.5xIQR or Q1-1.5xIQR.
  9. 19. 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.
  10. 20. a line that a given curve continually approaches but does not meet

  1. 1. A straight line that best represents the relationship between two variables plotted on a scatter plot.
  2. 2. 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.
  3. 4. The square root of a number 𝑥, is a number, 𝑦 such that 𝑦2 = 𝑥; in other words, the square root of a number is a number whose square is 𝑦 ∙ 𝑦.
  4. 5. 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. 8. 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.
  6. 9. The lowest point on a parabola.
  7. 11. A relationship where one variable's change directly results from the change in another variable.
  8. 12. Element in a sum, difference, or sequence.
  9. 15. The set of input values for which the function is defined.
  10. 18. The highest point of a parabola.
