Okay,now that result holds, right, for all erm for all marginal relationships Okay, so if we are looking at a marginal marginal cost curve , right, we have got that's our marginal cost , that's our average cost we, we're intersecting here when in the case it is a minimum so marginal costs cuts through average costs at its minimum value we are looking at average revenue and marginal revenue average revenue function marginal revenue function This is our total revenue function and the same relationship is embodied there, but, notice that between the average and the average revenue and marginal revenue functions, right, don't intersect simply because we have got a linear relationship here right, average revenue is always above marginal revenue in this particular case.
