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.
Okay well, just by looking at the graph. It’s a negative slope and the only answer, that has a negative is the 3 one.
4x3=12. The commutative property of multiplication says that two numbers can multiplied either way without getting another answer.
