Using the form y=a(x-h)²+k
We can look at the vertex (-3,-2) which gives us the values of h,k
h=3, k=-2
Thus y=a(x+3)²-2
Then we can solve for a using any point on the line
- I'll use (-4,-1)
Insert the values of x,y into y=a(x+3)²-2
--> x=-4, y=-1
y=a(x+3)²-2
-1=a(-4+3)²-2
-1=a(-1)²-2
a-2=-1
a=-1+2
a=1
Insert the value of a
y=1(x+3)²-2
= (x+3)²-2
Thus y=(x+3)²-2 is the final equation in standard form
Answer: If you mean by the B symbol next to a bunch of points. Those are points you can earn depending on the question. For example, if I helped someone with their problem, I would receive the amount of points that they put up for that question. I’m pretty sure the points can also help you to rank up and give you a new title or something. Im new myself lol

Answer:
The number of units sold increased by 
Step-by-step explanation:
Vacuum dealer sold units in 2011 = 420
Vacuum dealer sold units in 2012 = 467
We need to find percent increase or decrease
Since, In 2012 units sold are greater than 2011, so there will be percent increase.
The formula used is: 
We have New Value (Units sold in 2012) = 467
Original Value (Units sold in 2011) = 420
Percent increase is:
So, The number of units sold increased by
