show that the union of two jordan regions is a jordan region.
then give an example to show that the union of an infinite number of jordan regions is not necessarily a jordan region.

you can't solve x because it is 2 linear equation and you only have one equation

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

its a, i had the same answer, its from study island right
