• {-7, -1, -8}

• {-3, 6}

• {-3, 3, 6}

• All real numbers

Describe the end behavior of the graph.

• x →∞, y→∞ and x→∞, y→⁻∞

• x →∞, y→∞ and x→⁻∞, y→∞

• x →∞, y→∞ and x→⁻∞, y→0

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.
