I need help finding the line of symmetry to y=-2(x+1)^2+18.
**
Standard form of equation for parabola: y=A(x-h)^2+k, (h,k) being the (x,y) coordinates of the vertex.
For given conic is a parabola that opens downward and has a vertex at (-1,18)
The line of symmetry is a vertical line thru the vertex. Its equation: x=-1
