Honors Algebra II vocab 2026-2027

Domain

The set of all possible input values (x-values) for a given function, where each input corresponds to one or more outputs.

Range

The set of all possible output values (y-values) for a given function, determined by the corresponding inputs in the domain.

Slope-intercept form

A way to express a linear equation in the form $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.

Point-slope form

A way to express a linear equation in the form of y-y1=m(x-x1). Where m is the slope and x1 and y1 are points on the line. x,y are any variables representing a point on the line. *Use when you know the slope, and one point on the line.

Standard form

Ax+By=C

interval notation

() parentheses not included, {} brackets included

inequality notation

Uses algebraic symbols (<, >, ≤, ≥) with a variable (like x) to show the conditions of a number set. Example: x > 2.

Infinity

An unbounded, limitless quantity that goes on forever without end and is not a specific number.

Zero product Property

if any number in an expression is multiplied by zero, the product immediatly becomes zero.

What makes a function a function?

if every single input has ONE output value

What is another word for points of intersection?
