<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>
<em><u>Solution:</u></em>
<em><u>Given is:</u></em>

We have to find the vertex and axis of symmetry
<em><u>The general equation is given as:</u></em>

Comparing with given equation,
a = 2
b = 0
c = -1
<em><u>The axis of symmetry is given as:</u></em>


Thus axis of symmetry is 0
The x coordinate of the vertex is the same
x coordinate of the vertex = 0
h = 0
The y coordinate of the vertex is:
k = f(h)
k = f(0)

Thus, y coordinate of the vertex is -1
Therefore, vertex is (0, -1)
Divide 74 into 4 and 6
74/4 = 18,5
74/6=12,33
so if you buy in bags of 4 you need 19 bags, which costs 5 x 19 = $95
if you buy in bags of 6 you need 13 bags, which costs 7 x 13 = $91
Buying in bags of 6 costs less.
Distance formula= [(x2-x1)^2 + (y2-y1)^2]^1/2
Origin= white house = (0,0)
Capitol= (2300,800)
Put the value,
(2300² + 800² )^1/2
= 2435 meters
Thus distance is 2435 m
