[1] (value 10%)  If f (x) = (x + 1) e^{x} , 
then the one critical value of f is (enter a number) 
[2] (value 10%)  If f (x) = (x  1) e^{  x} , 
then the one critical value of f is (enter a number) 
[3] (value 10%)  If f (x) = x^{2} e^{x} ,  

[4] (value 10%)  If f (x) = x^{2} e ^{x²} ,  

[5] (value 10%)  If f (x) = x^{2} x (for x > 0), 
then the one critical value of f is (enter a decimal accurate to 0.01: answer is between 0 and 1) 
[6] (value 10%)  (see problem [1] above) If f (x) = (x + 1) e^{x} , 
then the one candidate of f is (enter a number) 
[7] (value 10%)  (see problem [2] above) If f (x) = (x  1) e^{  x} , 
then the one candidate of f is (enter a number) 
[8] (value 10%)  (see problem [3] above) If f (x) = x^{2} e^{x} ,  

[9] (value 10%)  If f (x) = e^{x}  e^{  x} , 
then the one candidate of f is (enter a number) 
[10] (value 10%)  (see problem 5) If f (x) = x^{2} x (for x > 0), 
then the one candidate of f is (enter a decimal accurate to 0.01: answer is netween 0 and 1)
