2) 4 is not a solution.
3) -1 is not a solution.
4) 0 is a solution.
5) 0.23 is not a solution.
6) 2/3 is a solution.
It will be approximately 5 hours and 30 min
F(x)=x^2+6x-2, vertex: (-3, -11)
First, put -(6)/2(1) or -b/2a.
You then get -3 as the X value of the vertex.
Next, insert -3 back into the equation to get the Y value of the vertex.
(-3)^2+6(-3)-2 = -11
You then have -11 as the Y value of the vertex.
