(MCA) 4.1 Plotting Points. Evaluating Functions.

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 in the form (x, y), where 'x' is the horizontal coordinate and 'y' is the vertical coordinate.

Front

What does the point (4, 6) represent on a graph?

Back

The point (4, 6) represents a location on the graph where the x-coordinate is 4 and the y-coordinate is 6.

Front

How do you evaluate a function at a specific point, such as g(-10)?

Back

To evaluate a function at a specific point, substitute the input value into the function's equation and simplify to find the output.

Front

What is the significance of the x-coordinate in an ordered pair?

Back

The x-coordinate indicates the horizontal position of a point on the coordinate plane.

Front

What is the significance of the y-coordinate in an ordered pair?

Back

The y-coordinate indicates the vertical position of a point on the coordinate plane.

Front

What is the ordered pair for point E if it is located at (-3, 0)?

Back

The ordered pair for point E is (-3, 0), where -3 is the x-coordinate and 0 is the y-coordinate.

Front

What does the ordered pair (-4, -4) indicate on a graph?

Back

The ordered pair (-4, -4) indicates a point located 4 units left and 4 units down from the origin (0, 0) on the coordinate plane.

Front

How do you identify a plot point from an ordered pair?

Back

To identify a plot point from an ordered pair, start at the origin (0, 0), move horizontally to the x-coordinate, and then vertically to the y-coordinate.

Front

What is the output of the function f(-2) if f(-2) = 6?

Back

The output of the function f(-2) is 6, meaning that when the input is -2, the function evaluates to 6.

Front

What does it mean if a function value is undefined?

Back

If a function value is undefined, it means that the function does not have a valid output for the given input, often due to division by zero or other restrictions.
