ANSWER
The vertex of the graph of

is

EXPLANATION
The vertex form of a parabola is given by

where

is the vertex of the parabola.
The function given to us is

This is already in the vertex form.
When we compare this to the general vertex form, we have,


and

Therefore the vertex of the parabola is

Hence the correct answer is option A.
Answer:
I dont know
Step-by-step explanation:
only doing it for points
Y= 2.50(x) + $20 is the linear equation
If 15 videos are rented
Y=2.50(15) + $20
Y= $57.50
67.50 = 2.50(x) + 20
19= x
19 videos were rented in 3 months
-6 / 2 = -3 so
x^2 - 6x + 8 is
(x - 3)^2 -9 + 8
= (x - 3)^2 - 1
the vertex is at (3,-1)
