M2 T3 Test Review

Front

What is the definition of a function?

Back

A function is a relation where every input has exactly one output.

Front

Which point can you REMOVE to make this a function?

Back

Point T can be removed to make the relation a function.

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 does it mean for a graph to be linear?

Back

A linear graph is a straight line that represents a linear function, which can be expressed in the form y = mx + b.

Front

If the input is 5, what is the output of the function f(x) = x - 3?

Back

The output is 2.

Front

What is an example of a non-function?

Back

A relation where an input has multiple outputs, such as a circle, is not a function.

Front

What is the range of a function?

Back

The range is the set of all possible outputs of a function.

Front

What is the domain of a function?

Back

The domain is the set of all possible inputs for a function.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

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

Back

A one-to-one function is a function where each output is produced by exactly one input.
