Linearity Unit Review

Is the following linear or non-linear: y=2-5x(y+2)

• linear

• nonlinear

Describe the graph as discrete, continuous, or discontinuous.

• Discrete

• Continuous

• Discontinuous

• Yes
• No

Determine whether the function is linear or nonlinear.

• linear

• nonlinear

Determine whether the function is linear or nonlinear.

• linear

• nonlinear

Determine whether the function is linear or nonlinear.

• linear

• nonlinear

Determine whether the function is nonlinear.

• linear

• nonlinear

Determine whether the function is discrete, continuous, or neither. Then determine whether the function is linear or nonlinear.

• discrete; linear

• neither; nonlinear

• continuous; linear

• continuous; nonlinear

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.

What is the domain of the graph?

• All real numbers

• To infinity and beyond

• y ≥ 0

• x ≥ 0
