G(x)=2x^2+2x-1
G(3)=2(3)^2+2*3-1=18+6-1=23

given G(x)=2x^2+2x-1
G(3)=2(3)^2+2(3)-1
=2(9)+6-1
=18+6-1
=24-1
=23

I'm assuming that you mean G(x) = 2x^2 + 2x - 1
G(3)) = 2 (3)^2 + 2(3) - 1
G(3) = 18 + 6 - 1
G(3) = 23

if that is
G (x) = 2x² + 2x - 1
then
G (3) = 2(3)² + 2(3) - 1
G (3) = 2(9) + 6 - 1
G (3) = 18 + 6 - 1
G (3) = 23

g(x) = 2x^2 + 2x - 1
g(3) = 2(3)^2 + 2(3) - 1
g(3) = 2(9) + 6 - 1
g(3) = 18 + 5
g(3) = 23

just substitute value of x=3 in equation i will get
2(3)^2+2(3)-1
18+6-1
23
therefore G(3)=23
