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 .
