Explanation:
A quadratic function can be written in vertex form as:
f
(
x
)
=
a
(
x
−
h
)
2
+
k
where
(
h
,
k
)
is the vertex and
a
is a constant multiplier.
In our example the vertex
(
h
,
k
)
is
(
3
,
4
)
, so we can write:
f
(
x
)
=
a
(
x
−
3
)
2
+
4
Given that this passes through the point
(
1
,
2
)
, we must have:
2
=
a
(
1
−
3
)
2
+
4
=
4
a
+
4
Subtract
4
from both ends to get:
−
2
=
4
a
Divide both sides by
4
and transpose to find:
a
=
−
1

So our quadratic function can be written in vertex form as:
f
(
x
)
=
−
1
2
(
x
−
3
)
2
+
4
We can multiply this out and simplify as follows:
f
(
x
)
=
−
1
2
(
x
−
3
)
2
+

f
(

Answer:
C. m = n
Step-by-step explanation:
lines m and n are parallel lines cut by a transversal l.
angles 1 and 5 are congruent corresponding angles.
The division is one of the four fundamental arithmetic operations. The rent of the flat for each month will be Rs. 30,000.
<h3>What is Division?</h3>
Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that the rent of the flat for one year is Rs. 3,60,000. Since a year has 12 months. Therefore, the rent for each month will be,
Hence, the rent of the flat for each month will be Rs. 30,000.
