ECON 1540U, Winter 2022, Assignment 1
1. Consider a Cobb-Douglas function of the form: z = x0 .75y0 .25 .
(a) Find the equation of the curve (call itC1) in the z − x plane along
which y = 16.
(b) Draw the (2-D) graph of C1 .
(c) Label the point on C1at which x = 1. Call this point P. What is the z − coordinate of P?
(d) Find the slope of the tangent to C1at P. Find the equation of the line that is tangent to C1at P .
2. Consider a Cobb-Douglas function of the form: z = x0 .75y0 .25 .
(a) Find the equation of the curve (call itC2) in the y − x plane along
which z = 1.
(b) Draw the (2-D) graph of C2 .
(c) Label the point on C2at which x = 16. Call this point Q. What is the y − coordinate of Q?
(d) Find the slope of the tangent to C2at Q. Find the equation of the line that is tangent to C2at Q.
