Solution

The correct option is C y=(x2)2
A. y=|x|2
Since the minimum value of |x| is 0, the minimum value of y becomes 2
B. y=x22
Since the minimum value of x2 is 0, the minimum value of y becomes 2
C. y=(x2)2
Any square number is non-negative and so the minimum value of y is zero.
D. y=x32
x3 can go upto negative infinity and so even y.
