4. A statement that two expressions are equal, often involving an unknown variable.
6. A number that indicates how many times a base is multiplied by itself.
8. A relationship where each input (x) has exactly one output (y).
9. Equation,A polynomial equation of degree 2 (highest power of x is 2), like ax² + bx + c = 0.
10. A statement that compares two expressions using symbols like <, >, ≤, or ≥.
12. The set of all possible output values (y) for a function.
13. The steepness of a line, calculated as the rise over the run.
14. A visual representation of a function or equation on a coordinate plane.
16. The set of all possible input values (x) for a function.
17. The distance of a number from zero on the number line (represented by |x|).
20. The solutions to a polynomial equation (also called zeros).

1. The numerical factor of a term (e.g., in 3x, 3 is the coefficient).
2. A symbol (usually a letter) that represents a number in an equation or expression.
3. Numbers that include real and imaginary parts (e.g., a + bi).
5. An expression with one or more terms, each consisting of a constant and a variable raised to a power.
7. A formula used to solve quadratic equations (x = (-b ± √(b² - 4ac)) / 2a).
11. The point where a graph crosses an axis (x-intercept or y-intercept).
