A parabola is a mirror-symmetrical U-shape.
- The equation of the parabola is
- The focus is
- The directrix is
- The axis of the symmetry of parabola is:
From the question, we have:
The equation of a parabola is:
Substitute the values of origin and vertex in
Collect like terms
Solve for a
Substitute the values of a and the vertex in
The focus of a parabola is:
Substitute the values of a and the vertex in
The equation of the directrix is:
So, we have:
----- the directrix
The axis of symmetry is:
We have:
Expand
Expand
A quadratic function is represented as:
So, we have:
Recall that:
So, we have:
This gives
Hence, the axis of the symmetry of parabola is:

Answer:
11(4h-3)
Step-by-step explanation:
The greatest known common factor of 44h and 33 is 11. So using the distributive property, I got 11(4h-3)
Looks like y = |x| because the slopes of the lines are both 1
You shift it to the right making it |x-2| and you shift it down making y = -2
combine to get <em>y = |x - 2| - 2</em>.
