You can put this solution on YOUR website!
F(X)=3X62+X
F(-1)=3(-1)^2+(-1)
F(-1)=3*1-1
F(-1)=3-1
F(-1)=2
#######################################
G(X)=8
G(2)=8 ARE YOU MISSING AN X IN THIS EQUATION?
########################################################3
THE ONLY POSSIBLE ANSWER I CAN COME UP WITH IS
G(2)=CUBE ROOT 8 OR 8^(1/3)
