FIVE FUN CHRISTMAS RIDDLES. HAVE FUN ANSWERING THEM. THEY'RE FOR FUN. 1. This ring is made of leaves,
Flowers, fruits, twigs, and more;
And then at wintertime
It hangs on your front door.
What could it be?

2. I’m a cookie you might like to eat,
Some might say I’m a favored Christmas treat.
I have brown arms, eyes, and don’t forget my feet.
What am I?

3. Dropping from the sky
More beautiful than rain
There are no two pieces
That’ll ever look the same
What am I?

4. I am a catchy carol and a tune which likes to rhyme,
I contain 12 gifts that come around Christmas time.
What am I?

5. I am a helpful creature
not too big and not too small
Out of all my fellow reindeer
I’m the fastest of them all.
Who am I?

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
