What is the vertex for the graph of y = 2x2 + 12x + 10?
|dw:1358913254412:dw|
first coordinate of the vertex of \(ax^2+bx+c\) is always \(-\frac{b}{2a}\)
in your case it is \(-\frac{12}{2\times 2}=-3\) second coordinate is what you get when you replace \(x\) by \(-3\)
you both gave good responses thank you ;)
