The zeros and the vertex of the parabola are x = -4 & x = -2 and (-3, -1), respectively
How to determine the zeros and the vertex of the parabola
From the question, we have the following parameters that can be used in our computation:
The graph of the quadratic function
Where, we have
zeros at x = -4 and x = -2
This is so because the graph crosses the x-axis at x = -4 and x = -2
Also, we have the vertex of the parabola to be
(-3, -1)
This is so because the graph has a minimum at (-3, -1)
