Given f(x) = ax2 + k (where f(x) is a quadratic),
describe when its reciprocal function would and would not have
vertical asymptotes. Refer to the values (+,-,0) of a and k in your
description. What are all the possible scenarios?

Consider the following growth function for fish given by F( X )
= rX(1 − X/K) where the intrinsic growth rate r = 0.2 and the
carrying capacity K = 100 tons of fish. Let the harvest function be
given by H = qEX where the catchability coefficient be q = 0.01 and
H is harvest in tons of fish.
Compute the following:
a. The maximum yield of fish at the steady state.
b. Effort and Harvest when the price...
Consider the following production function: x = f(l,k) =
lb kb where x is the output, l is the labour
input, k is the capital input, and b is a positive constant.
Suppose b < 1/2.
(a) Set up the cost minimization problem and solve for the
conditional labour and conditional capital demand functions. Let w
and r be the wage rate and rental cost of capital respectively.
(b) Using your answer in (a), derive the cost function and
simplify...

The Quadratic equation is used to solve for the variable x where
the function evaluates to zero. However there is actually two
answers returned by the quadratic equation. Can we solve for the
quadratic equation using just one call to a function you write?
Hint : create a function that does not 'return' anything. Takes
three parameters a,b,c as double.s
And had two more parameters that are passed by reference to two
doubles that are the two answers...

b. Clearly state the critical number(s) of the function.
c. Find the relative extrema of the function( using 1st
derivative test). answer should be in (x,y)
