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.
