Given:
The equation of a quadratic function is:
To find:
The equation of the axis of symmetry for the given function.
Solution:
If a quadratic function is 
, then the equation of the axis of symmetry is:
...(i)
We have,
Here, 
. So, the equation of axis of symmetry by using (i), is
Therefore, the correct option is C.
Answer: GR = 27
Step-by-step explanation:
Given: R is the midpoint of FG.
i.e. R bisects FG into two equal parts as FR and GR. [Midpoint divides a line into two equal parts.]
or we can write FR = GR
Since it is given that FR = 27
Then from (i) , GR = FR = 27
i.e. GR = 27
Hence, GR = 27 , which is the required solution.
YQ/SQ = JB/DB
YQ/72 = 60/45
YQ = 72*(60/45) = 96
