Front

This is an example of a graph that is not a function because it fails the vertical line test. True or False?

Back

True

Front

Solve the equation: 4x + 10 = 2(2x + 5)

All real numbers

Front

What is the domain and range of the relation? {( -3, 5), (4, 0), (0, -5)}

Back

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 intersects the graph more than once, it is not a function.

Front

Define domain in a function.

Back

The set of all possible input values (x-values) for the function.

Front

Define range in a function.

Back

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

Front

What does it mean for an equation to have 'no solution'?

Back

There are no values for the variable that satisfy the equation.
