Given the equation of the parabola:

The general form of the given equation will be as follows:

We will write the given equation to be like the general form

the graph of the parabola will be as follows:
So, the given equation represents a parabola with the following properties:
1) The axis of symmetry is parallel to the x-axis and opens right
2) The coordinates of the vertex = (-3, -1)
3) The equation of the axis of symmetry: y = -1
4) a = 4/3
5) The equation of the directrix: x = h - a ⇒ x = -4 1/3
6) The direction of the opening is right
