Front

What is a function?

Back

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

Front

What is the definition of a non-function?

Back

A non-function is a relation where at least one input has more than one output.

Front

What does the inequality 6 > x mean?

Back

It means that x can be any number less than 6.

Front

What does the graph of x=2 represent?

Back

It represents a vertical line that crosses the x-axis at 2.

Front

How do you find the equation of a line parallel to another?

Back

The slope of the parallel line is the same as the original line.

Front

What is the slope of the line represented by y = 2x + 1?

Back

The slope is 2.

Front

What is the equation of a line passing through (2, -1) with a slope of 2?

Back

y = 2x - 5.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What does -3 < y < 3 represent?

Back

It represents all y-values that are greater than -3 and less than 3.

Front

What is the difference between domain and range?

Back

Domain is the set of all possible input values (x-values), while range is the set of all possible output values (y-values).
