Front

Is this graph a function or not a function?

Front

A relation where every input matches with exactly one output is called what?

Back

Function.

Front

Evaluate f(-5) if f(x) = -2x - 12.

Back

-2.

Front

f(x)=4x-22 solve for f(10).

Back

18.

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is the 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 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
