U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2

Answer:
C
Step-by-step explanation:
plug the first point in (0), cancels out B, D, E bc g(x) doesnt equal to -1
now the two left are A and C, plug in 1, A doesn't work because 1^2-1=0, not 1
C works because 2(1)-1 = 2-1= 1
