Answer:
Plot these points
(-3,0)
(-5,0)
(-4,1)
(-2,-3)
(-6,-3)
Step-by-step explanation:
Let find the zeros of the equation.
We can factor this equation.
Factor out the -1.

Factor using AC method

Set all the terms equal to zero.




So our x intercepts are -3,0 and -5,0.
To find our vertex, apply the -b/2a.

Then
Substitute-4 for x.

So our vertex is at (-4,1).
Find some other points like -2 and -6.
To find -2, substitute-2 into the quadratic.

So -2,-3.
Since y=-4 is the axis of symmetry
-6,-3
