Show as we did for indifference curves, under what conditions we expect that (Hint: in your answers, you should, where appropriate, be referring to concepts such as the marginal rate of technical substitution, marginal product, transitivity, and so on): (1) Isoquants slope downwards. (ii) Isoquants further from the origin represent higher output. (iii) Isoquants cannot intersect. (iv) Isoquants are convex.
