Answer:
Vertex form: 
Standard form: 
Step-by-step explanation:
A quadratic function in vertex form is
where
is the vertex.
We are given
.
Let's plug that in:
.
Now let's find
.
We will use the
-intercept
to find
.






So the function in vertex form is:
.
In standard form, we will have to multiply and combine any like terms.
Let's do that:

13 its not hard aslo give n if not no one can figure it out
13/ 52 = 1/4 chances.
There are 13 spades and 52 cards. You divide the spades and cards in the deck to find your chances of drawing one.
You have a 25% chance of getting a spade.
Now you put it back. Since you put it back, you still have the same number of cards and the same number of spades. So when you divide 13/52 again, the numbers are still the same. 1/4. 25% chance.
So, you still have a 25% chance the second time around.
