so
and
solving the 2 equations for the 2 variables:
Answer:
D
Step-by-step explanation:
Quadratic has a general form of:
The quadratic given here is:
Matching it with the general form, we can see that:
a = 1 [coefficient of x^2]
b = 3
c = 1
Now, if we look at the formula for axis of symmetry, we can easily solve this out. The axis of symmetry is given by:
Axis of Symmetry is
We know a = 1 and b = 3, so we have:
Hence,
D is the correct answer.
