Solution:Property of Isoquants (the production IC):
• An Isoquant curve slopes downward, or is negatively sloped,
• An Isoquant curve, because of the MRTS effect, is convex to its origin.
• Isoquant curves cannot be tangent or intersect one another.
• Isoquant curves in the upper portions of the chart yield higher outputs.
• Isoquant curve should not touch the X or Y axis on the graph.
• Non-Intersecting and non-tangential
Therefore, concave to the point of origin is not a property of Isoquant.
