What is the DOMAIN of a graph?

Back

The domain of a graph is the set of all possible x-values (inputs) for which the function is defined.

Front

What is the zero of a function?

Back

The zero of a function is the x-value where the function's output (y-value) is zero, meaning the graph intersects the x-axis.

Front

What is a function?

Back

A function is a relation that assigns exactly one output (y-value) for each input (x-value).

Front

What is the Y-INTERCEPT of a graph?

Back

The Y-intercept is the point where the graph intersects the Y-axis, represented as (0, y).

Front

How do you solve a system of equations by substitution?

Back

To solve by substitution, solve one equation for one variable, then substitute that expression into the other equation.

Front

What does it mean for a graph to be continuous?

Back

A continuous graph has no breaks, jumps, or holes; you can draw it without lifting your pencil.

Front

What is the difference between a linear function and a non-linear function?

Back

A linear function has a constant rate of change and graphs as a straight line, while a non-linear function does not.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written as (x, y).

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables that are solved together.
