- 3. a letter used to represent an unknown numerical value in an equation or expression
- 5. a polynomial equation where the highest power of the variable is 2
- 6. replacing the variables in an algebraic expression, equation or inequality
- 7. Opposite of Negative
- 15. a mathematical statement that expresses equality between two expressions, separated by an equal sign ("=") where both sides can include variables, numbers, and operations, allowing you to solve for the unknown variable value(s)
- 17. where you actually eliminate one of the variables by adding the two equations
- 18. a mathematical concept that represents the distance of a number from zero on a number line, always resulting in a non-negative value, regardless of its sign
- 21. the set of all possible input values (usually represented by the variable "x") that can be plugged into the function without causing any mathematical errors
- 22. a line on a coordinate plane used as a reference point to determine the position of a point
- 23. a statistical method that uses a straight line to model the relationship between two variables, where one variable (dependent) is predicted based on the value of another variable (independent), by finding the "best fit" line that minimizes the distance between the line and data points
- 24. the lowest point on a graph of a function
- 26. two lines that never intersect each other and have the same slope
- 28. a way of writing a quadratic equation where the coordinates of the parabola's vertex (the highest or lowest point on the graph) are easily identifiable as the values "h" and "k" in the equation
- 29. a number that indicates how many times a base number (the number being multiplied) should be multiplied by itself, written as a superscript number next to the base
- 30. a technique used to factor trinomials (expressions with three terms) of the form "ax^2 + bx + c", where the key step is to multiply the coefficient "a" with the constant term "c" and then find two numbers that multiply to this product and add up to the middle coefficient "b
Down
- 1. a set of rules dictating the sequence in which mathematical operations (like addition, subtraction, multiplication, division, exponents) should be performed within an expression
- 2. a number that is multiplied by a variable in an expression
- 4. a number that, when multiplied by itself, gives the original number
- 8. the rules that tell us the sequence in which we should solve an expression with multiple operations
- 9. if solving it leads to a false statement
- 10. the highest value a function reaches within a given set of inputs
- 11. represents the vertical or perpendicular distance of the point from the origin or from the x-axis
- 12. the measure of how steep a line is on a graph, calculated by dividing the change in the y-values (rise) by the change in the x-values (run) between any two points on the line
- 13. he set of all possible output values (y-values) that a function can produce
- 14. Opposite of positive
- 16. a special way of writing numbers or equations that helps us easily compare and work with them
- 19. represents the distance of the point from the origin or along the horizontal x-axis
- 20. First, Outer, Inner, Last
- 25. the line which makes a right triangle with the coordinates axes, with the sides of lengths as 'a' units and 'b' units respectively
- 27. the visual representation of a function on a coordinate plane, where each point on the graph corresponds to an ordered pair (x, y) that satisfies the equation of the function, essentially showing how the output value (y) changes based on the input value (x)
