function in vertex form is:
vertex is: (8,5) and is a minimum on the graph.
axis of symmetry is x=8.
Hence is the vertex form of the given function g(n).
B: Hence the vertex of any equation of the type is given by (h,k)
so, the vertex here is :(8,5)
this is a upward open parabola so the vertex has a minimum hence (8,5) are the minimum point of the graph.
C: The axis of symmetry of a parabola is a straight line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola.
here the axis of symmetry is a vertical line that passes through the vertex.hence the value of x is fixed.
so equation of axis of symmetry is:
