  2. 7. Property A mathematical principle stating that multiplying a sum by a number is equivalent to multiplying each addend by that number and then adding the products.
  3. 9. To explain or understand the meaning of something, such as data or a mathematical result.
  4. 12. The highest or lowest point on a parabola, where the direction of the curve changes.
  5. 14. A mathematical statement that asserts the equality of two expressions, typically separated by an equal sign (=).
  6. 15. To express or depict an idea, number, or object using symbols, figures, or equations.
  7. 17. To discover or identify a value or solution through calculation or search.
  8. 19. Variable The variable in a function or equation that is manipulated or changed to observe its effect on the dependent variable.
  9. 21. The point where a graph intersects the y-axis, representing the value of the function when the independent variable is zero.
  10. 23. Like Terms The process of simplifying an expression by adding or subtracting terms with the same variables and exponents.

  1. 1. Many Solutions A situation in a mathematical equation where there are unlimited solutions, often occurring in equations that are identities.
  2. 2. A visual representation of data or mathematical functions, typically in the form of points, lines, or curves on a coordinate plane.
  3. 3. of Operations A set of rules that indicate the sequence in which operations should be performed in an expression, typically remembered by the acronym PEMDAS.
  4. 4. Graph A graph composed of distinct, isolated points, representing data that can only take specific values.
  5. 6. To establish or ascertain something through calculation, examination, or investigation.
  6. 8. To find the answer or explanation for a problem or question, often involving mathematical operations.
  7. 10. To calculate the value of an expression by substituting values for variables and performing the operations.
  8. 11. A symbol, often a letter, used to represent an unknown or changeable value in mathematical expressions or equations.
  9. 13. A single mathematical expression, which may be a number, a variable, or a product of numbers and variables.
  10. 16. A symmetrical, U-shaped curve representing the graph of a quadratic function.
  11. 18. Variable The variable in a function or equation whose value is determined by the value of another variable (the independent variable).
  12. 20. A combination of numbers, variables, and operations (such as addition or multiplication) that represent a value.
  13. 22. Graph A graph that represents a function where small changes in the input result in small changes in the output, with no breaks or gaps.
