Function Review Part Two

Front

What is a dependent variable?

Back

A dependent variable is a variable that depends on or is changed by another variable in an experiment or equation.

Front

What is an independent variable?

Back

An independent variable is a variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

On which axis is the independent variable plotted on a graph?

Back

The independent variable is plotted on the x-axis.

Front

What does it mean if a graph shows a flat line?

Back

A flat line on a graph indicates that there is no change in the dependent variable; it is constant.

Front

What is the relationship between the independent and dependent variables?

Back

The independent variable is manipulated to observe how it affects the dependent variable.

Front

If Sarah is not moving on a graph, what does that indicate about her speed?

Back

It indicates that her speed is zero; she is at rest.

Front

What does it mean to accelerate?

Back

To accelerate means to increase in speed or velocity over time.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time.

Front

If Sophie earned $5 for every A on her report card, what is the dependent variable?

Back

The dependent variable is m = money, as it depends on the number of A's.

Front

What is the purpose of a graph in representing data?

Back

A graph visually represents data to show relationships between variables and trends over time.
