Day 81 - 8.PFA.3 - Functions Practice

Front

What is the range of a relation?

Back

The range of a relation is the set of all output values (y-values) that correspond to the input values (x-values).

Front

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

Back

A mapping is a function if each input value (x) is associated with exactly one output value (y).

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate plane, written in the form (x, y).

Front

What is a mapping diagram?

Back

A mapping diagram visually represents the relationship between input values and output values, showing how each input is paired with an output.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line, represented by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the domain of a function?

Back

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

Front

What is a table of values?

Back

A table of values is a way to organize input-output pairs of a function, showing how each input corresponds to an output.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal axis (x-axis) and a vertical axis (y-axis).

Front

What does it mean for a graph to be non-linear?

Back

A graph is non-linear if it does not form a straight line, indicating that the relationship between the variables is not constant.
