Given algebraic equations, need to graph the marginal product and average product for linear short-run, quadratic short-run, and cubic short-run production functions. Plug in numbers to graph. See attachment.Thank you.

Production Functions (Algebraic)

Graph the marginal product (MP) and average product (AP) for each of the following equations by plugging in numbers. (Graph the highlighted equations).

1. Linear Short-run. N = labor
a. MP n = the change in output / the change in labor
= dQ / dN = b

b. AP n = Q / N = a/N + bN/N
= a/N + b

Example: Supppose b = 10 10 + 5/1 = 15
a= 5 10 + 5/2 = 12 ½
N = 1 10 + 5/3 = 11 2/3

Make Y-axis Q (output) and X-axis N (labor) and graph.

Q = a + bN - cN²

a. MPn = dQ/dN = b - 2cN

b. APn = Q/N = a/N + bN/N - CN² / N

= a/N + b - CN

3. Cubic Short-run
Q = a + bN + cN² - dN³

a. MPn = dQ/dN = b + 2c&#8319; - 3dN²

b. APn = Q/N = a/N + bN/N + CN²/N - dN³/N

= a/N + b + CN - dN²
