What is the minimum point of the graph of the equation
y = 2x^2 + 8x + 9?
I understand the minimum point is the vertex (h, k).
To complete the square, I set the function to zero first.
2x^2 + 8x + 9 = 0
I then subtracted 9 from both sides.
2x^2 + 8x = -9
I then took half of the second term and squared it.
2x^2 + 8x = 16 - 9
Where do I go from here?
