Let f(x)=x^(2)+3x-3, x ge0 if in points x_(1),x_(2),x_(3),...x_(n) are so chosed on the x-axis such that (i) (1)/(n) underset(i=1) overset(n)sumf^(-1)(x_(i))=f((1)/(n)underset(i=1) overset(n)sumx_(i)) (ii) underset(i=1) overset(n)sumf^(-1)(x_(i))=underset(i=1) overset(n)sumx_(i) wehre f^(-1) denots the inverser of f. then mean of x_(1),x_(2),x_(3),....x_(n) is :
