Answer:The equation of the parabolic function is :[tex]y=(x-1)^2-3[/tex]Step-by-step explanation:The standard equation of a parabola is given by:[tex]y=a(x-h)^2+k[/tex]where [tex](h,k)[/tex] represents the vertex of the parabola.From the graph shown in figure we can find the vertex of the parabola which is the minimum point of parabola and lies st point [tex](1,-3)[/tex]So, we can say: [tex](h,k)\rightarrow (1,-3)[/tex]Plugging in the values of vertex in standard equation of parabola,[tex]y=a(x-1)^2+(-3)[/tex]Simplifying the equation:[tex]y=a(x-1)^2-3[/tex]We can find value of [tex]a[/tex] by plugging in a point from the graph.Using point (0,-2) which lies on graph.Plugging in the given point.[tex]-2=a(0-1)^2-3[/tex][tex]-2=a-3[/tex]Adding 3 to both sides.[tex]-2+3=a-3+3[/tex][tex]1=a[/tex]∴ [tex]a=1[/tex]Plugging in [tex]a=1[/tex], the equation of parabola can be written as:[tex]y=(x-1)^2-3[/tex]
