Answer: First option is correct.
Step-by-step explanation:
Since we have given that
If the factored form is given by

Then its standard form will be given by

if factored form is given by

Then its standard form will be given by

Hence, only first option is correct.
Answer:
axis of symmetry is
.
The ordered pair of the vertex is
.
Step-by-step explanation:
Your function is a quadratic.
Compare
to
.
You should see that
.
The x-coordinate of the vertex or the axis of symmetry since the axis symmetry goes through the vertex can be found by computing
.
So here we go!
The axis of symmetry is
.
When you write your axis of symmetry be sure to write it as an equation.
That is the axis of symmetry is
.
Now that was also the x-coordinate of your vertex. To find the corresponding y-coordinate of the vertex, plug your value for
into
.

Put into calculator:
when 
The ordered pair of the vertex is
.
Dont think theres enough info there to do that
