Answer:
We can also find the vertex by using the expressions:
(
−
b
2
a
,
f
(
−
b
2
a
)
)
Standard form:
a
x
2
+
b
x
+
c
=
0
In this example,
a
=
−
1
and
b
=
0
x
=
−
0
2
(
−
1
)
=
0
2
=
0
y
=
f
(
0
)
=
7
−
0
2
=
7
Same result of
(

From colonial times into the early 20th century a majority of americans lived in the countryside and worked on farms. A dramatic expansion in farming took place from 1860 yo 1910. The number of farms tripled from two million in 1860 to 6 million in 1905. The number of people living on farms grew from about 10 million in 1860 to 22 million in 1880 to 31 million in 1905.
