we have the function
This is a quadratic function (vertical parabola) written in vertex form
y=a(x-h)^2+k
where
(h,k) is the vertex
In this problem the vertex is the point (-6,-2)
Make a table
For x=-4
substitute the value of x in the function
g(-4)=-(-4+6)^2-2
g(-4)=-6
For x=-2
g(-2)=-(-2+6)^2-2
g(-2)=-18
For x=0
g(0)=-(0+6)^2-2
g(0)=-38
For x=2
g(2)=-(2+6)^2-2
g(2)=-66
Graph the function
Plot the points and join then to find the graph
we have the points
(-6,-2)
(-4,-6)
(-2.-18)
(0,-38)
(2,-66)
