CCSS.HSF.IF.A.2

Is the function continuous, discrete, or neither? Explain.

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

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

• Discrete; because the function is made up of individual segments and rays, it is discrete.

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

CCSS.HSF-IF.C.7B

Is the function continuous, discrete, or neither? Explain.

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

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

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

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