Is It a Function Discrete

Determine whether the function is discrete, continuous, or neither. Explain.

• Continuous; because the function is made up entirely of individual points, it is continuous.

• Continuous; because the individual points could be connected with a single line, the function is continuous.

• Discrete; because the function is made up entirely of individual points, it is discrete.

• Discrete; because the function is not graphed with a single line or curve, it is discrete.

Determine whether the function is discrete, continuous, or neither. Explain.

• Discrete; because the function is not graphed with a single line or curve, it is discrete.

• Discrete; because the domain of the function is not all real numbers, it is discrete.

• Neither; because the function is not graphed with a single line or curve, it is neither continuous nor discrete.

• Neither; because the function has continuous sections but is not a single line or curve, it is neither continuous nor discrete.

Kalynda keeps track of the number of cups of flour she has after baking batches of cookies and then graphs the function that models the situation. Use the graph to determine if the function that models this situation is discrete, continuous, or neither.

• continuous

• discrete

• neither

Rashona keeps track of the total number of minutes she exercises and then graphs the function that models the situation. Use the graph to determine if the function that models this situation is discrete, continuous, or neither.

• continuous
