xsqaure+x+1=f[2x-1]

f[2x-1]=[2x-1]square+[2x-1]+1

=4xsq.-2x+1

by using the formula,x=-b+_sq.root of bsq.-4ac\2a

=2+-i sq. root of 12\8

hey mate!

according to the question,

f(x) = f(2x - 1)

then,

2x-1 = 0

=> 2x = 0+1
=> x = 1/2

now,

f(x) = x² + x + 1

f(1/2) = (1/2)² + (1/2) + 1

= 1/4 + 1/2 +1/1

= (1+2+4)/4

= 7/4 ........Ans.
