The range is all real numbers.

• Trick

• True

The function is decreasing.

• Trick

• True

As x increases, y decreases.

• Trick

• True

The graph is decreasing.

• Trick

• True

The function is positive when x > 1.2.

• Trick

• True

The domain is
x ≥ 0.

• Trick

• True

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
