[1] (value 10%)  If f (x) = 2x^{2} + 8x + 3 , 
then the one critical value of f is (enter a number) 
[2] (value 10%)  If f (x) = x^{3}  6x^{2} + 12x + 6 , 
then the one critical value of f is (enter a number) 
[3] (value 10%)  If f (x) = x^{3} + 3x^{2}  9x + 12 ,  

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

[5] (value 10%)  If f (x) = x^{4}  4x^{3}  8x^{2} + 48x + 4 , (see a similar example above)  

[6] (value 10%) 


then the one critical value of f is (enter a number)
