Question a b c d

Question 1

Question 3

Question 4

Question 5

1. Given the linear map : ^ → , whose associated matrix is given by 

= ^ −

A. We

conclude that: a. dim(ker( f ))= 2 b. Ker ( f )= {( x , y , z )∈ R^3 / xz = 0 ; y = 0 } c. Dim(Im(f)= d. None of the above answers is correct.

  1. Consider the following quadratic form:  , ,  ^  ^  ^ ^  . Choose the correct answer among these statements: a.  is always Positive Definite if a =b. b.  is Indefinite since the associated matrix has two identical eigenvalues and a^2 –b^2 is never negative. c.  is Negative Semidefinite if a is nil (Zero) and b <. d. Q is always Positive Definite for any a>b.
  2. Choose the correct answer among the followings. Given the following cost function   , with k

any positive constant. Then: a. The marginal value of the cost with respect to the output (Q), is always negative for  0. b. The elasticity of the cost function is equal to -. c. The answers a) and b) are correct. d. There is no enough information to tell about the behaviour of marginal-value and elasticity functions.

  1. Assess the correct definition. Given the following definite integrals   ^   20and  ^   10 a.  ^      10. b.  ^      30. c. (^)  ^   5   30 d. None of the above is true.

5. Let us consider S, a set defined by : S = {( x , y , z )∈ R 3 / x + y + z = 0 ; 2 x − ay = 0 }. Then

a. For all ! 0, S is a subspace from R^3 , with the dimension equal to 2. b. For a =0, S is a subspace from R^3 with dim(S) =

c. For a = 5 , S is not a subspace from R^3

d. None of the above is true.
