A PPF is the locus of points such that all the economy's resources are used to its fullest potential. A PPF is concave to the origin because of the increasing opportunity cost to produce an additional unit of x (on the horizontal axes). A point inside the PPF is attainable because (1) there may be no full employment or (2) inspite of full employment they are used to less potential. On the contrary a point outside the PPF is not attainable because the PPF itself is the locus of the maximum attainable output given resources, the PPF may however expand due to increase in resources or their efficiency.
Attainable, but the economy is inefficient.
it represents the boundary between the goods that are attainable and unattainable within an economy. Inside and along the ppf means that goods are attainable and outside the ppf menas the goods are unattainable and it thereby shows scarcity
under what conditions an econoy would be operating inside its production possibility frontier?
This is known as the law of diminishing returns and can occur because factor on the frontier is deemed to be production efficient and production inside frontier.
A point inside a production possibilities curve represents things that can be produced. However, points inside the curve would be less efficient to produce than those points resting directly on the line.
Attainable.
below or to the left of the production possibilities frontier

An economy working below its most efficient production levels points inside the production possibilities frontier. This is in the context of a production possibilities curve.
This is known as the law of diminishing returns and can occur because factor on the frontier is deemed to be production efficient and production inside frontier.
A point inside a production possibilities curve represents things that can be produced. However, points inside the curve would be less efficient to produce than those points resting directly on the line.
A point inside the PPF means that resources are not being used efficiently. One or more resources (Land, labor, or capital) is being waisted or not used to its potential. More of both goods could be produced than are currently being produced.
If there are opportunity cost, then yes my friend, they do.
At any point of underutilization/any point inside of the curve
That is true :)
