A graph plots marginal and average product versus inputs of labor. 2 curves labeled marginal product and average product are graphed.The horizontal axis is labeled, inputs of labor. The inputs of labor Q 1, Q 2, and Q 3 are marked on the horizontal axis from left to right. The vertical axis is labeled marginal and average product. The graph shows 2 curves labeled marginal product and average product. The curve labeled marginal product starts at a point on the bottom left, goes up and to the right with increasing steepness until it reaches a point, goes down and to the right, crosses the horizontal axis at (Q 3, 0), and extends below the horizontal axis. A vertical dashed line extends from Q 1 to the maximum point of marginal product. The curve labeled average product starts at the bottom left goes up and to the right, intersects the curve labeled marginal product at Q 2 and, then goes down with decreasing steepness. A vertical dashed line extends from a point near the end of the curve to Q 3. Refer to the diagram, where variable inputs of labor are being added to a constant amount of property resources. Average
