discrete/continuous function with Domain and Range

Is the graph pictured discrete or continuous?

• Discrete
• Continuous

Discrete or Continuous?

• Discrete
• Continuous

Discrete or Continuous? The correct answer is (a)   .

• Discrete
• Continuous

Is this discrete or continuous?

• discrete
• continuous

• Discrete

• Continuous

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.

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.

• 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 two separate rays, it is neither continuous nor discrete.

• Neither; because the range of the function is not all real numbers, it is neither continuous nor discrete.

• {-2, 3, 7}
• [-2, 3]
• {1, 2, 2, 3, 4}
• [1, 4]

The range is (a)   .

• {-3, -1, 2, 4}
• {0, 4, 7} 
• {0, 4, 4, 7}
• {7, 4, 0}
