ANSWER
EXPLANATION
The given function is
Let us split the middle term to get,
We factor to obtain,
Let us find the zeros of f(x),
Either
We need to find the x-value of the vertex, which is the midpoint of the x-intercepts.
This gives us,
Hence the axis of symmetry of the parabola has equation,
Since the given function has minimum turning point, it will decrease and then increase.
The function will be increasing for
The function will be increasing and positive for

Answer:
Equation of the parabola is
Step-by-step explanation:
We have to find the equation of a parabola with vertex is (-4,-3) and a directrix x=2.
As vertex is (-4,-3) that means parabola is in third quadrant.
So the standard formula of the parabola will be y²= -4px through origin (0,0).
But when a parabola is shifted from origin to the left of y axis so the equation will be (y-shifting form y axis)² = -4(distance between vertex and directrix)(x-shifting from x axis)
