1. Relation A set of ordered pairs that associates elements from one set to elements of another.2. Function A relation where each input (domain) has exactly one output (range).3. Domain The set of all possible input values for a function.4. Range The set of all possible output values of a function.5. One-to-One Relation A relation where each input corresponds to a unique output, and no two inputs share the same output.6. One-to-Many Relation A relation where one input is related to multiple outputs.7. Many-to-One Relation A relation where multiple inputs correspond to the same output.8. Many-to-Many Relation A relation where multiple inputs can correspond to multiple outputs.9. Vertical Line Test A visual test to determine if a graph represents a function; if any vertical line crosses the graph more than once, it is not a function.10. Polynomial Function A function made up of terms consisting of variables raised to whole number powers and coefficients, combined using addition, subtraction, and multiplication.11. Linear Function A polynomial function of degree 1, with the form [tex]\( f(x) = mx + b \)[/tex].12. Quadratic Function A polynomial function of degree 2, with the form [tex]\( f(x) = ax^2 + bx + c \)[/tex].13. Cubic Function A polynomial function of degree 3, with the form [tex]\( f(x) = ax^3 + bx^2 + cx + d \).[/tex]14. Constant Function A function where the output value is the same for all inputs, [tex]\( f(x) = c \)[/tex].15. Monomial A polynomial with only one term, e.g., [tex]\( 5x^3 \)[/tex].16. Binomial A polynomial with two terms, e.g., [tex]\( 3x + 4 \)[/tex].17. Trinomial A polynomial with three terms, e.g., [tex]\( x^2 + 5x + 6 \)[/tex].18. Set A collection of distinct objects or elements, usually enclosed in curly braces [tex]\(\{\}\)[/tex].
