Honors Functions Review

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce based on its domain.

Front

What is a function?

Back

A function is a relation that assigns exactly one output value for each input value.

Front

What does it mean for a graph to be a function?

Back

A graph represents a function if every vertical line intersects the graph at most once (Vertical Line Test).

Front

What are the coordinates of Quadrant III?

Back

Quadrant III contains points where both x and y coordinates are negative.

Front

How do you determine f(0) from a graph?

Back

To find f(0), locate the point where the graph intersects the y-axis.

Front

What is the correct way to plot the point (4,9)?

Back

To plot (4,9), move 4 units to the right (x-axis) and 9 units up (y-axis).

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

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

Back

A graph is 'not a function' if there exists at least one vertical line that intersects the graph at more than one point.

Front

What are the four quadrants of the Cartesian plane?

Back

Quadrant I: (+,+), Quadrant II: (-,+), Quadrant III: (-,-), Quadrant IV: (+,-).

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the output value when the input is zero.
