$y=2x^2+3$ The standard form for a quadratic equation is $y=ax^2+bx+c$ So a= 2, b= 0, and c= 3 Axis of symmetry: The formula for axis of symmetry is $$x=−b/2a$$ $$x=−0/2(2)$$ $$x=0$$ Vertex: Plug in the x value of the axis of symmetry to find the y value of the vertex. $$y=2x^2+3$$ $$y=2(0)^2+3$$ $$y= 0 + 3$$ $$y= 3$$ The vertex is (0,3)
