Functions or Not: definitions, vertical line test,map & evaluate

Front

What are all of the y values or outputs in a function called?

Back

Range

Front

What does the vertical line test determine?

Back

Whether a graph represents a function or not.

Front

What is the definition of a function?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

Is the relation {(2,3), (2,4)} a function? Why?

Back

No, because the x-value 2 has two y-values (3 and 4) paired with it.

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 range of a function?

Back

The set of all possible output values (y-values) for the function.

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

D: {0, 1, 2, -4}, R: {1, -3, -4}.

Front

Is the table of values below a function? {(1,2), (2,3), (1,4)}

Back

Not a Function, because the x-value 1 has two y-values (2 and 4).

Front

What is a relation in mathematics?

Back

A set of ordered pairs (x, y).

Front

What does it mean if a graph passes the vertical line test?

Back

It means that the graph represents a function.
