Exercises: Recognize Constant Rate Situations

The slope is the output value when the input is zero.

The slope is the constant amount the output changes for each unit increase in the input.

The slope is the percentage the output increases each period.

The slope is the largest output value in the function.

The function is exponential because the outputs are increasing.

The function is linear because the first differences are constant (+3 each time).

The function is exponential because the ratios are constant.

The function is neither linear nor exponential.

A population doubles every 5 years.

A savings account earns 3% interest each year.

A runner covers 6 miles per hour.

A car depreciates 12% annually.

This is an exponential situation because the cost increases each time.

This is a constant rate situation because the same amount ($0.05) is added for each text.

This is a constant percent rate situation because $0.05 is a small number.

This is neither linear nor exponential because the cost depends on usage.

A bacteria colony triples every 2 hours.

A city grows by 2% per year.

A car rental costs $45 per day.

An investment loses 8% of its value each quarter.
