How do you find the height of water in a draining bathtub after a certain time?

Back

To find the height of water after a certain time, refer to the graph that shows the rate of drainage. For example, if the graph indicates that the water level decreases by a certain amount per hour, multiply that rate by the number of hours.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run). A slope of 'undefined' occurs when the line is vertical.

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 the range of a function?

Back

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

How do you determine if two ratios are equivalent?

Front

What does it mean for a function to be undefined?

Back

Front

What is the difference between independent and dependent variables?
