The standard form or the equation of a parabola is y = 7x^2 + 14 +4. What is the vertex form of the equation? Can someone please explain how to get the answer. I am having a difficult time understanding the concept. Answers choices: y = 7(x + 2)^2 - 3 y = 7(x + 2)^2 + 3 y = 7(x + 1)^2 - 3 y = 7(x + 1)^2 + 3
