Find the vertex of the graph of the equation....

1. \(x - y^2 + 8y = 13\)

2. \(y = -2x^2 + 8x - 15\)

Arrange first one as x = y^2 -8y+13 then the 'y' value of the vertex will be found (this is a sideways parabola)

as - b/2a where b =** - **8 a =1 use THIS value in the equation to find the 'x' value

y = -2x^2 + 8x -15 vertex 'x' value will be -b/2a b = 8 a = -2 use THIS value in the equation to find the vertex 'y' value

Beats me .... What did YOU find after I told you HOW to get the answer? I'm not here to puke up answers to people's homework
