Functions or Not Functions Quiz

What is a mapping diagram?

• A visual representation of a function showing how each input is paired with an output.

• A chart that lists all possible inputs and outputs without any connections.

• A graphical representation of data points in a scatter plot.

• A diagram that illustrates the steps in a mathematical proof.

What is an example of a function?

• The equation y = 2x + 3 is a function.

• The equation y = x^2 + 5 is a function.

• The equation y = 1/x is a function.

• The equation y = sin(x) + cos(x) is not a function.

What is the range of a function?

• The set of all possible input values (x-values).

• The set of all possible output values (y-values).

• The difference between the maximum and minimum values of the function.

• The slope of the function at a given point.

What is a non-function?

• A relation where at least one input has multiple outputs.

• A relation where each input has exactly one output.

• A function that does not have a defined output.

• A relation that is always increasing.

How can you tell if a graph represents a function?

• By checking if it has a maximum or minimum point.

• By using the vertical line test; if a vertical line crosses the graph more than once, it's not a function.

• By ensuring it is a straight line.

• By counting the number of points on the graph.

What is an ordered pair?

• A pair of numbers (x, y) that represents a point on a graph.

• A single number that indicates a position on a number line.

• A set of three numbers that defines a point in three-dimensional space.

• A pair of letters used to denote a coordinate in a grid.

What is the domain of a function?

• The set of all possible output values (y-values).

• The set of all possible input values (x-values).

• The range of the function.

• The maximum value of the function.

Can a function have the same output for different inputs?

• No, a function cannot have the same output for different inputs.

• Yes, a function can have the same output for different inputs.

• A function can only have unique outputs for unique inputs.

• It depends on the type of function.

What does it mean for a function to be one-to-one?

• Each output is paired with exactly one input.

• Each input can have multiple outputs.

• All outputs are the same for different inputs.

• The function is defined for all real numbers.
