Help does anyone know a lot about higher index radicals and solving them? I don't understand how to solve with the variables. I don't know whether to put them inside or outside of the root, and I don't understand which power to put them to. Someone please, please help. It would be greatly appreciated.

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
