Functions

Front

What is the definition of a function?

Back

A function is a relation where every input has only ONE output.

Front

Which of these is NOT the same as the others: Range, Input, Dependent Value, Y-Value?

Back

Input is NOT the same as the others.

Front

Is this graph a function or not a function? (Graph shows a vertical line)

Back

Not a Function.

Front

What is the range of this function? (Function defined from 150 to 275)

Back

[150, 275]

Front

Is this graph a function or not a function? (Graph shows a horizontal line)

Back

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 difference between independent and dependent variables?

Back

Independent variables are inputs (x-values), while dependent variables are outputs (y-values) that depend on the inputs.

Front

What does it mean for a function to be linear?

Back

A linear function creates a straight line when graphed and has a constant rate of change.

Front

What is a vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

Front

What is a one-to-one function?

Back

A function where each output is paired with exactly one input, meaning no two different inputs produce the same output.
