a) open upwards
b) Vertex: (-2, -1)
c) x intercept: -
d) the equation of the axis of symmetry is x = -2
Step-by-step explanation:
a) The parabola opens upward
b) The vertex is the tip of the parabola.
The tip of the parabola is at ( -2, -1)
Vertex: (-2, -1)
c) The x intercepts are the values of x when the line crosses the x axis
The crosses the x axis at x = -1 and x = -3
x intercepts: -1 , -3
y intercept is the value of y when the line crosses the y axis
It crosses it at y = 3
y intercept: 3
d) The axis of symmetry is the value of y that causes the parabola to splitinto equal halves
It is also the value of te x coordinate of the vertex
At x = -2, the parabola can be split into two equally
Hence, the equation of the axis of symmetry is x = -2
