Which of the following fractions are closer to 1/3:

10/31 20/61 30/91 40/121 50/151

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
