How does the graph of y=-(2x+6)^2+3 compare to the graph of the parent function?
a) the graph is compressed horizontally by a factor of 2, shifted left 3, reflected over the x-axis, and translated up 3.

b) the graph is reflected over the x-axis, compressed horizontally by a factor of 2, shifted left 6, and translated up 3.

c) the graph is stretched horizontally by a factor of 2, reflected over the x-axis, shifted left 3, and translated up 3.

d) the graph is reflected over the x axis, stretched horizontally by a factor of 2, shifted left 6, and translated up 3.
