Question

1.    Find the extremums of these functions:
(a)     у = 3х2 + 9х - 14;           у = 2х3 + 3х2 -5;        у =3х4 - 12х3+ 9;  
(b)     у = -2х2+ 4х+ 5;           у = х4 + х2;            у = х3 + 3х2 - 9х - 11;  
(c)    у = х2/3 + х1/3;                у = х2/3(х-10)        у = х4 + х2;   
(d)    у = х3 + 3х2 - 9х - 11;   у = х2/3 + х1/3;              у = х2/3(х-10).
