Given the points from a quadratic function.

Firstly, let us plot the points;

Above is a graph shown each of the ponts;

a) The vertex of the function.

It is the point at which the function on the graph changes direction.

For the given function, the vertex is at point;

[tex](0,7)[/tex]

b) The equation od the axis of symmetry.

this is the line that divides the function on the graph into two equal halves.

For the given function, the axis of symmetry is at;

[tex]x=0[/tex]
