A = 2
b = 2
c = -4
"a" is greater than zero so the vertex is a minimum point and the graph is concave up.
The (x,y) point of the vertex is usually designated by the letters (h, k)
The "x" position (or "h") is calculated with this formula:
h = -b / 2a
h = -2 / 4
h = -1 / 2
"k" is calculated with this equation:
k = ah^2 + bh +c
k =(2*-1 / 2 * -1 / 2) + (2 * -1 / 2) + -4
k = (1 / 2) - 1 -4
k = -4.5
so the vertex is at point (-.5, -4.5)

Answer:
The interest is equal to ![\$13](https://tex.z-dn.net/?f=%5C%2413)
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Find the interest
![I=A-P=\$92.61-\$80=\$12.61](https://tex.z-dn.net/?f=I%3DA-P%3D%5C%2492.61-%5C%2480%3D%5C%2412.61)
Round to the nearest whole dollar
![\$12.61=\$13](https://tex.z-dn.net/?f=%5C%2412.61%3D%5C%2413)
The answer is 9,850 if you are adding the numbers together.
