Is this function linear or nonlinear?

• Linear
• Nonlinear

Is this function linear or non-linear?

• LInear

• Non-linear

Is this function linear or nonlinear?

• Linear function

• Nonlinear function

Which graph(s) show nonlinear functions? [Check all that apply]

• Graph I

• Graph II

• Graph III

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.

• Continuous; because the function is graphed with a single curve, it is continuous.

• Continuous; because the domain of the function is all real numbers, it is continuous.

• Neither; because the function is graphed with a single curve but the range does not include all real numbers, it is neither continuous nor discrete.

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