Step-by-step explanation:
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:



$85.20/6= $14.20/pair is the answer because unit price equals cost/pairs
The altitude might be another name for a height of a pyramid, lol, hope this helps
2x - 2y = 2
2x - 2 x 0 = 2
2x - 0 = 2
2x = 2
x = 1
2x - 2y = 2
2 x 0 - 2y = 2
y = - 1
