Question 619902
Y=-2xsquared-2x-7 write in vertext form and tell me the vertex please
----
y = -2(x^2 +x + ?) -7 - (-2*?)
---
y = -2(x^2 + x + (1/4)) - 7 - (-2(1/4))
---
y = -2(x+1/2)^2-7 + 1/2
---
y = -2(x+(1/2))^2 - (13/2)
----
Vertex: (-1/2 , -13/2)
------
{{{graph(400,400,-10,10,-10,10,-2x^2-2x-7)}}}
