Equation of a parabola in vertex form is y=(x-h)^2+k.
where (h,k) is the vertex.
6) The given equation is y=[tex]-2x^{2}+2.[/tex]
Comparing with vertex form of parabola equation we have:
This has a vertex of (0,2)
Graph A has the same vertex (0,2)
7) Given equation y=[tex]-x^{2}[/tex]
As there is a - sign so parabola will open down and vertex is (0,0)
Graph D is the right graph.
8) Given equation is : y=2[tex]x^{2}.[/tex]
The vertex is (0,0) and parabola will open up.
Graph C represents the same.
9) The given equation is :y=3[tex]x^{2}.-4[/tex] Its vertex is (0,-4)
THis graph is B .
