What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is interval notation?

Back

Interval notation is a way of writing subsets of the real number line. It uses parentheses ( ) for open intervals and brackets [ ] for closed intervals.

Front

What does it mean if a function is defined for all real numbers greater than 7?

Back

It means that the function's input values can be any number greater than 7, but not 7 itself.

Front

How do you find the price per pound of an item using a system of equations?

Back

Set up equations based on the total costs and quantities, then solve the system using substitution or elimination.

Front

What are perfect squares?

Back

Perfect squares are numbers that can be expressed as the square of an integer, such as 0, 1, 4, 9, 16, 25, etc.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

How do you determine the slope of a line from its equation?

Back

In the slope-intercept form of a line, y = mx + b, 'm' represents the slope.

Front

What is the slope of the line given by the equation y = 5x + 4?

Back

The slope of the line is 5.

Front

What is the difference between open and closed intervals in interval notation?

Back

Open intervals use parentheses ( ) and do not include the endpoints, while closed intervals use brackets [ ] and include the endpoints.
