What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

How can you determine if a relation is a function from a table?

Back

A relation is a function if no x-value is repeated with different y-values.

Front

What does it mean if a relation is 'not a function'?

Back

It means that at least one x-value is associated with more than one y-value.

Front

What is the vertical line test?

Back

A graphical method to determine if a curve is a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The set of all possible output values (y-values) for the function.

Front

What is a linear function?

Back

A function that graphs to a straight line, represented by the equation y = mx + b.

Front

What is the slope of a line?

Back

The slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

What does the y-intercept represent in a linear function?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

What is a quadratic function?

Back

A function that can be expressed in the form y = ax^2 + bx + c, where a ≠ 0.
